Is it OK here to ask which on-line sources sell keto friendly foods?

Moderators, if this is out of line, feel free to nuke this thread, I won't be insulted -- just not sure of the rules.

I have no financial ties with any companies, just want to know where to shop on-line as local stores around me have an extremely limited selection.

I do Netritition and Amazon.

Anything else out there that is better? Better selection? Better prices?

Thanks,
Bob
