Resources for Authorized Retailer model?

Hi all,

Long time SaaS startup junky, but now building my first business: an e-commerce authorized retailer.

Most of the resources I find online are either for DS models, and/or often focused on a small selection of white labelled, highly marketed products.

My business serves the upper half of a niche market (sim racing hardware) where the prices are pretty high (most orders are between $500-$1,500).

There is a lot of competition in this space, with shrewd buyers who generally already know what they want, and are just looking for the cheapest price. So this makes positioning and differentiation difficult.

I've found a couple areas that are under exploited (one being a huge focus on customer advisory and satisfaction).

Overall, I feel like I've been successful so far, but when I try to self-educate, I'm struggling to find resources that feel like they apply to my model.

Does anyone have any recommendations for resources? Or perhaps work in a similar niche who would be open to chatting a bit?

There's a lot of stuff that I've just had to figure out on the fly (things like how to negotiate authorized reseller deals, how to work with OEMs) and while I think I'm doing okay, I'm very much "winging it".

thanks for reading!
