I gave away my Joann fabrics Coupons

I have lots of joann fabrics coupons because my mother shop there often times and gets lots of coupons but I don’t use them because I don’t buy anything on that shop so the coupons my mom gave to we was useless. But I feel bad about wasting the coupons because I think you can save a lot using them so I gave them to my girlfriend and surely when I told her about giving her the coupons my mom gave me she got psyched and told me to go out the next day. I said ok so we went to joann fabrics and craft store the next morning and looked around. She then start buying all kinds of stuffs. She bought 2 cross stitches, bunches of yarns, knitting needles and a pair of scissors. When we showed the tickets it was all valid so my girlfriend got a huge discounts on the items she bought.
