My first purchase of coupons

After reading Krazy Coupon Lady's book. I bought coupons on ebay today for the first time ever. It is so weird. I'm buying $2/1 All detergent. I'm going to try to price match all detergent at walmart or target with the big lots ad ($2.50) and use the 2 coupon to get them for $.50!! I'll let you know.
