Why does the same Google Workspace plan cost $2 in one place and $8 in another?

Ran into something that didn't make sense to me at first and wanted to see if anyone here has actually dealt with it.

Google's own pricing for Workspace is $8 to $28 per user per month, depending on the plan. But if you look at resellers, the same product, same Gmail, same Drive, same admin console, shows up priced anywhere from $2 to $7. No feature difference that I could find. Just a completely different number depending on who's selling it.

Turns out the explanation is pretty simple once you dig into it: Google has an actual partner program that sells Workspace licenses to authorized resellers at a wholesale rate below what individual customers pay directly. Resellers then set their own retail price on top of that. Some pass most of the discount back to the customer and make money on volume. Others price closer to Google's own rate and lean on support instead. Underlying product doesn't change either way.

What I'm more curious about, and why I'm posting this here instead of just writing it up somewhere, is whether people who've actually gone through this have found the cheap resellers to be legit long-term, or whether there's a catch that only shows up after you're already signed up. The obvious warning sign I did find is any reseller offering a one-time "lifetime" payment for permanent access, since Google bills resellers regularly forever, so that offer structurally can't be sustainable no matter who's making it.

For anyone who's actually switched from Google's direct pricing to a reseller: was the admin experience the same, did support hold up, and did the price actually stay where it was quoted after the first renewal? Trying to figure out if the savings are worth the switch or if there's a hidden cost I'm not seeing yet.
