I purchased an INTEX inflatable airbed at Shopko on March 7 for 39.99 which was a 20% off the regular price. I also used a $10 coupon which I had from purchasing 10 presciptions from their pharmacy.

I was told I couldn't get an adjustment/refund because I had used the additional coupon from business in the pharmacy. read full review »
