I purchased some shorts for my son as a Christmas gift and they were on sale. After the holidays I found he needed a size larger and tried to do an exchange. System showed that larger size I wanted wasn't available, but I WAS able to order them. (Funny, not available for an exchange, but available as a new purchase at full price!!) I decided to go ahead and order since they were available and thought for sure that Gymshark would refund me the difference of over $13. I contacted them (only option is through chat) and they just gave some bologna about me purchasing at a time when there wasn't a sale and they couldn't provide a refund for the difference!!! An exchange should be even for the same shorts, different size!!! I'll never order from them again and would encourage others to steer away!! Thank you.
