EASY to order!

Very fast shipping

Easy process, looking forward to receiving it!

All good

Was bothered about the shipment coming with a lot of damage to the box and it had foot prints all over it. I reached out with concern and was told I could return it but will be charged to restock/service. This is uncool considering the condition it arrived in from the warehouse or etc.

Easy to order

Very easy and good price

Great price and refrigerator was delivered promptly. Would definitely recommend Boatplicity to a friend
