Walgreen adventure

So...this morning I went to Walgreen's just to get their Arizona Tea they had on sale for 2 /1.00, but there was a limit of four. I asked the guy up front if I used 5 coupons, could I get 20 of them at the sale price, he said no problem, I'll just scan the same coupon. I got 20 Arizona Teas for 10.00 and 5-32 oz. Gatorade's for 5.00 and I also got 2 candy bars for 1.00, so all in all, I saved 16.57 on my total bill!! It's nice to know that some places will let you slide! I am going back tomorrow to get 20 more.....
