What stores do accept online printable coupons?

What do stores accept as coupons printed off a coupon site?

• Has anybody used coupons that you print off from coupon sites for products? If so; when given to the cashier at the check out, do they have to be coloured ink or could it black ink? Do they have to be printed on white paper? I have only black ink at the moment and a whole box a green computer paper to use up.

• Answer:

  most places like walmart, need it to be colored. there needs to be that watermark when you hold it up to the light, that way they will know if its a fradulent coupon or not. (basically if you scanned it a crap load and printed them). make sure you read the fine print on each coupon. some places only let you use it at certain grocery stores/supermarkets. just as long as the coupon has that watermark, you'll be fine! :) i'm not too sure on the colored paper thing, i've never encountered this at my job. you can print a coupon on colored paper to see if you can still see that watermark. good luck! :)
