If you find yourself coming to Sumo every week, let alone multiple times a day, then most likely you NEED to just join Plus. That 10% on 1 code on 1 deal is no big deal...but like how often does that happen? Most of us-I made up the estimate of half of you reading this-buy 1 code on tons of stuff and a few times a year you do a full stack on different things. Guess what? 10% off pays for itself pretty quick.
The simple math is "if you spend $1k in 1 yr then plus makes sense" and yes, that is the obvious math. The less obvious math also includes the Plus Exclusives-at any given time there are 3-5 extremely good ones-that also exist on the regular side of the site. Well the plus version is always cheaper and has more features. If you buy 1 then you save another $10-50+.
The you add in the 72 hrs extra on select deals and it gets a bit better. That 1 deal that slipped through....it doesnt slip through.
Oh and what about Last Call? You get stuff that is not available anymore at the LTD rate and will never be available again at LTD pricing. This last one made it worth it to me (Jan 2022)
Finally they seem to be building out a plus community that has some good assets and could become even better.

If you do the simple math you probably need Plus, if you do the extended math it looks even more enticing, and if you add in the optionality of what it could become? It is a no brainer for most return site visitors.

idk I saved enough from buying mine in about 2 weeks. There was a deal I wanted to full stack and a few more I needed more codes. I bought one code in the morning and then got thinking "wtf Dave you are burning money" and signed up to for Plus and never turned back.
