Anyone sell fairly niche high ticket price electrical goods on Amazon?

I do quite well selling them through Shopify and I use Amazon for FBA only really.

Amazon keep trying to get me to spend some money on advertising but I can’t see me getting my money back.

I can’t see people buying specialist items like that on Amazon. I wouldn’t. Because I’d want some customer support also.

Any insight would be very much appreciated !

I agree I defo would not spend more if you are not seeing a return. However, optimising any ads and ppc can make a huge difference to the efficiency of how your budget it used
