Tip: Combine your discount card fobs into a single wallet-sized card

[parnass]

The plastic discount card fobs distributed by stores are prone to breaking off a key ring.  I kept a collection of these card fobs strung together by a small cord in my wallet until I devised a better solution.

I cut down 4 discount cards, making sure to leave the bar codes intact, then laminated them into a single wallet-sized card for ease of carry.  Staggering the discount cards prevents the stores' bar code scanners from confusing adjacent cards.

You can also just print the bar codes on a sticker/label yourself. Just generate the bar code with some software program

As Reinier points out, you can print your own. There is a free font floating around that will do that simply (using Word, Notepad, or whatever). Also, the vertical height of the bar code is not important, so long as there is enough for the person to accurately line up the scanning laser with it. One thing I've seen done is to have a circle with a bunch of codes printed on it (again, since you don't have to make them very tall, a 2-3 diameter circle can hold quite a few codes) then have a second wheel over top with only a small slit cut out. The two wheels are joined at there center by a brad. Then you just rotate the wheel to the code you need and can scan it without accidentally scanning another one. You could probably do something similar with a square card by having it slide.

Also, I like how redacted your card numbers. Worried someone might steal them and rack up PetPerks for you???

Thanks for the alternative suggestions.  As you've shown, "there is more than one way to skin a cat," although they seem like more complex solutions to a simple problem.
