I had no idea this could even happen and don’t at all understand the math (I got several for different amounts even though it’s all resulting from PT appointments that cost the same). But it is a very small and unexpected joy this week.
Somehow I accidentally ordered the wrong contacts which ended up being a really expensive mistake. Customer service graciously paid for my shipping label, I sent it back, and I just got the reimbursement for it. I feel rich even though it was already my money.
