Depends on if you have a bot/scraping problem or not. Though admittedly sitting behind something like Cloudflare and leveraging their reputation system rather than blithely embedding recaptcha into your page might be the way to go, but then you're married to Cloudflare. Pick your poison.

Apart from the caveat I gave regarding logins, there is simply no such thing as a bot or scraping "problem" for a web store. Your goal is to advertise what you are selling far and wide - bots are your friends. If you have problems with site load, the first thing to do is make your site more efficient. If you're a small operation and that still isn't enough, add generic server side throttling.
