I bought shoes on eBay, and on the auction, they were clearly stated for size 37's. When i received the shoes they were 37.5. and they ended up being too big on me. I sent the seller an email requesting for a refund based on the fact that she said they were 37 and she agreed. But she she also said, that she was going on vacation starting saturday (tomorrow) and wont be back for 2 weeks. I told her i can ship them out today for saturday priority so she can get them before she leaves but she has not replied. Should I ship the item back right away or wait until she gets back from vacation? thanks!!
