Radio Shack 1.99 warranty/return scam Laguna Niguel, California

Radio Shack ripped me off... I purchased among other items, a cell phone cover priced on sale at 19.99 The sales person offered me a 1.99 warranty which would allow me to return it for any reason within a years time if it was defective, if i didn't like it any longer, etc. etc. I feel for it hook line and sinker... When I returned to the store in Laguna Niguel, without the box or faded receipt, I was told they could not locate the purchase on their computer records. 

The salesman asked me if I purchased a few other items (like I remember everything i ever bought with the cryptic description they give). After being put through the paces to remember, I was told I would have to return the item, wait for an email from the warranty company, and print off the coupon I would receive in a few days, then go back in to receive a gift card, and use the gift card if I wanted.

How the heck does that work when I would be without a phone cover until I can make another trip back to purchase another one that might cost more than the one I need to return? Furthermore, the store manager would not be available to talk to for two more days. So I left with the same cover only to return since it stretched out in more than thirty days ( which is the return policy of the store) . 

This is just unacceptable. I cannot return it with or without the box or receipt, regardless of having the warranty. What good is the warranty if i have to wait until I'm emailed the proper coupon? Wait an inefficient use of my time and resources. They are not taking responsibility for their products is basically what that says to me.  Selling me a warranty makes them money, most will not wait for the coupon, which allows them to make and extra 2 bucks on a 20 dollar item. Scam Scam Scam!!!!!! I would like my 19.99 back and the 2 dollar warranty price just for the inconvenience.
