Not an AIBU, but just wanted to warn people so they don't get caught out.
Many stores now offer a click and collect service which is great. However, I and many others have clicked but then not collected as we have found a better deal en route and then can't be bothered to go to the store to collect and return.
Recently, I have found that if I haven't collected my item I haven't got an automatic refund. One department store refused to issue it as the item had been destroyed and they couldn't process a refund without the item. Another department store only refunded me after I contacted customer services 3 weeks after the item would have been returned to the warehouse. With one toy company, I had to fight for 3 months.
Obviously, the ideal solution is only use the service if you will 100% pick it up, but just wanted to warn people to keep an eye on bank statements - I suspect many stores are hoping that with such a high volume of purchases at this time of year customers won't notice that they haven't been refunded.
