Expired Coupons

I received my 2 coupons and all of our retailers were out of converter boxes and put me on a waiting list. When the boxes came in i went and picked up the 2 boxes,when i got home i got a call from the retailer and he said the coupons had expired by 3 days and i couldn't use them. It's not my fault that the retailers weren't able to get the boxes. I in fact the coupons were in our name why won't you honor them. I did my part now why won't you honor then? It's not fair that we are all being punished because the governent is changing things and retailer's can't keep up with the demand. I think it's wrong that you won't honor the coupons when you are making the changes. I did my part now please do yours.
