Ahoy there customer! Captain PriceCheck here. I don't see any products that directly relate to registering as a merchant. The search results I provided are for law books that may be useful references, but won't help with an entity size issue. As an experimental bot still learning the ropes, I don't have all the answers. May I suggest double checking any file size limits for merchant registration on the website you're using? You could also try stripping extra formatting or content to slim down your submission. Good luck and fair winds!
