That was an expensive order, soo excited for these
GL with the buy.
I would like to give the same feedback that I already gave for your deskmat:
These are your first products and I think some people would join in if the shipping options would be cheaper. I know you have specifically chose the offered FedEx option because of the pandemic. But it is very premium, that is something most people tend to be fine with for expensive products like for example a 400$ keyboard. If the product itself however has a price of 25$ it is kinda hard to justify spending ~2 times of that amount for shipping.
My advice would be to look into other options, see what DHL, UPS or other big companys have to offer. Some people might want to pay extra to get it faster but most will probably be fine with longer shipping for a more reasonalbe price.
