I wouldn’t eat food from a place called Bottom Dollar. You get what you paid for, and that’s a pay that says “not fit for human consumption”. They very well might have just run out of the bags. Our dollar stores (where I like to buy DVDs, such a fun random selection) do weird unprofessional stuff like that all the time, I’ve seen them with only 1 door unlocked, no manned registers, they’re very easily confused.
Why not? All the packaged foods are the same as in the regular full service markets. A Perdue chicken is the same chicken as in the more expensive ones - just $1.00/lb cheaper. I just checked the 'Bottom Dollar' flyer - they have Hellman's mayonnaise for $3.77 - the other guys are $4.99 - I know where I would shop.
