6.99 is 6.99. It's only 7 if you pay with cash.

Regardless, 6.99 is so close to 7, that simply making it 7 is more honest. I'll pay the extra cent for the increased honesty/clarity.

And yes with 1 product it is still relatively easy (provided you put effort) but the more you buy in the grocery store the less oversight you get.
