I know when the Amazon email warning customers that they haven't received their orders is sent to my customers because I get several refund requests and quite often are worded like this:

"Amazon told me to ask for a refund"

"Amazon I haven't received my order"

When all the items, sent with ordinary RM 48, have been delivered according to RM. I even lost an A-Z recently with the buyer never actually saying that they didn't receive the order but that Amazon said they hadn't received it. According to RM it was delivered on time. Do all these people live in a palace or a castle so large that they are genuinely unaware that something was delivered?

To be honest I am tempted to stop selling small items on Amazon and focus on products that are expensive enough to justify the cost of tracking. I don't have this problem on eBay, where very rarely something is lost. I sell the same products, packed in the same way, sent through the same Royal Mail OBA and yet RM manage to lose so many LLs addressed to Amazon's customers and hardly any addressed to eBay's customers.

This is nothing new I know, it's costly but also upsetting because I know I have been scammed.
