Hi Orchid, I agree with your desire not to use credit cards at the grocery store. I too, think it is a "slippery slope" from a money management point of view -- and just generally a bad idea -- to buy necessities with credit.

But I was pretty sure the self-check machines DO accept cash. So I went and searched on Google, and found this "eHow" article which tells how to use coupons at the machines.

In the step-by-step directions, it mentions that you have to select your method of payment, and indicates that "cash" is one of the options.

SO: Not that I'm advocating that you use these self-check lines -- because Lord knows, I have been avoiding them, and you ought to know by now that I certainly wouldn't advocate that you do something I won't -- but it does seem that they DO accept cash.
