I'm not one to buy for the express purpose of getting a reward but tonight we were at our local drug store and a poster advertised a $20 gas card if we spent $75.
We were there to see if our vitamins were really on sale. I needed to get some face cream plus other household stuff. And another big reason to go was so I could prepay for the Harry Potter DVD coming out this week.
All in all, we ended up spending around $95 and received the gas card. It was a lucky stumble upon tonight. With gasoline prices on the up and up, a gas card is a valued reward for preplanned spending.
