Most Amazon Marketplace sellers don't socialise with other Amazon sellers. I was exactly the same until recently, however I recently began reaching out to other marketplace businesses I admired. It has been a fascinating, invaluable and very mutually-beneficial process.
Join our group to discuss challenges you are facing, things that are working well for you, and provide tips to other sellers. I have contact with Amazon UK at a Director level, and will look to help you with *business critical* issues that Amazon Seller Central Support isn't providing adequate support on.
Unlike other groups, our meet-ups will have no sponsor speeches to endure....just impartial, open discussion :)
