Does anyone know a proven method?
No one can help you.
You need to contact Lego and work out a deal.
We just bought from the Lego website and it worked
But amazon want approval letter.
They won’t give you approval letter.
That’s simple! Buy at least 10 units of any LEGO product from LEGO company. Once you have the invoice apply for approval. They will do.
Also there are some businesses on the market that offer support for ungating brands. EE distributor also does that.
Only way to get brand approval is through contacting Lego directly.
You can use harrisonsdirect
Provide invoice with all your company information with 10 units of lego, it will work. It has to be from an official distributor.
Get 10 lego keychains from lego site. 50 quid all in, thats what I did.
Make sure the exact item is selling on Amazon. Then provide your invoice copy to Amazon.
