I recently started selling on amazon US and to my surprise I get a lot of orders. The items I sell are letter size so they are posted as a small letter by royalmail but royalmail has threatened to ruin my business by not delivering on time. I spend £7 on postage per item and estimated delivery time is 3 to 7 days from the UK to the US. I spend around £4000 each month on postages yet royalmail never deliver on time, it takes royalmail more than a month to deliver each item which is way beyond their 3 to 7 days estimated delivery. Some buyers after being tired of waiting start asking for a refund and amazon straight away refunds any buyer who complains. I seriously don’t know what to do.
I’ve tried to do prime but haven’t found any courier that will deliver to amazon warehouse US, one that I found (woodlands?) charged nearly $600 on less 4kg weight of merchandise.
I need a reliable courier other than royalmail to send items to the US or a courier that will ship to amazon US warehouse with a reasonable price.
Thank you in advance.
