'ZDNET Recommends': What exactly does it mean?
ZDNET's recommendations are based on many hours of testing, research, and comparison shopping. We gather data from the best available sources, including vendor and retailer listings as well as other relevant and independent reviews sites. And we pore over customer reviews to find out what matters to real people who already own and use the products and services we’re assessing.
When you click through from our site to a retailer and buy a product or service, we may earn affiliate commissions. This helps support our work, but does not affect what we cover or how, and it does not affect the price you pay. Neither ZDNET nor the author are compensated for these independent reviews. Indeed, we follow strict guidelines that ensure our editorial content is never influenced by advertisers.

You're at a store and about to check out. The person behind the counter starts telling you about their store credit card and how it will save 30% on your purchase today or it'll immediately give you $25. It's certainly tempting. After all, if you just sign your name here and fill out this form, you get to keep more of your hard-earned money in your pocket. Why shouldn't you do it?
Often, people say no because they're in a rush, or they assume there's some catch in the fine print, and they just don't want to deal with it. Sometimes, people do sign up to get those extra savings.
Are the cards worth it, though? For the most part, they're not.
Store credit cards are cards that only work at one retailer or a group of retailers. For instance, the Target RedCard is used for 5% off purchases at Target stores. After purchases are charged to the card, it works much like a regular credit card in that cardholders have to pay off the balance lest they risk hits to their credit scores.
Sometimes, but most of the time, they are not. If you frequent a grocery store that has its own store credit card, it can be a good idea to have one. However, depending on the card's rewards offers, you could also be better off getting a credit card with 5% back at any grocery store -- that way, you're not limited to just one chain.
Unless you are making an enormous purchase, the actual amount you save with a store credit card signup bonus is tiny. It's usually just a tiny fraction of the amount of your purchase. Sure, it's savings, but the savings are minimal in the big scheme of things, and that small positive rarely outweighs the big negatives.
This is especially important when you consider that bonus in comparison to the reward you're already getting from your primary card. If the signup bonus is 10% off, but you're already getting 2% or 3% cashback on your card, you're really only getting a 7% or 8% bonus for the signup.
Often, that welcome bonus encourages people to do a little last-minute, unplanned shopping. If you go into a store planning to spend $200 and there's a last-minute discount, people tend to try to get more stuff with the $200 they've set aside rather than be happy that they're only spending $160 now.
The problem is that those final few purchases are usually very unplanned and poorly considered. If there's a purchase that's going to wind up being stuffed in a closet and forgotten about in a few weeks, it's this one. If there's ever an item you're going to spend your money on only to find it in the back of the closet in a couple of months as you wonder why you ever got this, it's this kind of last-minute purchase.
You are far better off avoiding last-minute purchases, and these kinds of credit card signups strongly encourage you to make those kinds of unplanned purchases.
Many in-store credit card signups offer you an initial reward for signing up, but then the ongoing benefit from the card is very limited. Often, that ongoing benefit comes in the form of a "points" program where purchases on the card give you a tiny amount of credit at that store (often 1% of your purchase price) or offer you a discount just at that retailer.

The truth is that there are many, many better rewards credit cards out there that will give you much better ongoing rewards than that. By simply finding a rewards card that pays well at most of the places you shop and keeping the balance on that card paid off every month, you're going to accrue far more rewards over the long run by simply using that rewards card everywhere.
If you're buying something that you won't be able to pay off immediately, you'll find that in-store credit cards tend to have poor interest rates. This means that interest will accumulate rapidly on the card if you don't pay off that balance quickly.
In fact, given the small reward that many such cards offer, simply carrying a balance for a few months will almost always cost you far more than the initial reward was worth.
Some cards offer an initial 0% interest rate to tempt you, but that teaser period is usually quite short, meaning that the overall savings are pretty small unless you are making a huge purchase.
An additional factor to consider is the extra identity theft risk that comes with every card you sign up for. Every credit card you have represents an account at a bank somewhere that could be hacked and a credit card number that could be stolen and used for undesirable purposes. The fewer credit cards you have, the better in terms of identity theft.
If you are considering signing up for a new card, simply having that new card at all is a slight negative because of that identity theft risk.
There are a few, but they're not spur-of-the-moment events to save $20 at the checkout.
The best reason to sign up for a store-branded credit card is if it offers a reward program related to that retailer that will save you more money than other rewards cards. This typically happens when you use that particular retailer a lot because it is your primary grocery store or gas station, or both. An example of this might be a Costco Anywhere Visa if you do most of your grocery shopping and gas purchases at a Costco and occasionally eat at restaurants. In that specific situation, the Costco card is very competitive.
However, you should decide to switch to a store-branded card away from the checkout. If a clerk springs a credit card offer on you, just say no unless you've already planned to sign up for the card.
