Living Well at Vons

I tried the living well promotion at Vons but ran into some difficulty. I got my first purchase OK but the second time I tried I didn't get my $10 off coupon. It was late so there wasn't a manager that could help me and I just returned everything. One of the checkers helping me read the fine print and said that you can only do one transaction per day per household. I guess I will be borrowing my husband's Vons card. I am not convinced that this promo is the best deal- Vons seems to be so expensive.
