Since you're asking for a Team Low Buy opinion, I'd ask what you're hoping to accomplish this year. Meet a certain maximum number of items purchased or budget goal? Shrink your collection? Only you can say whether purchasing a couple of these would fit in with your goals.
Seven seems like a lot to me given the size of your stash, but I don't know how quickly you go through them. Gloss is the item that I've had go off on me more than any other; I'm lucky to get two years out of it. If you've already got 80, how many of them are still good? How many do you really like? Would buying more cause you to not reach for the ones you have? Are you ok with tossing out glosses that are still good because you've found something you like better? Are these really
so much better that it's worth tossing out the money you've spent?
Personally, I'd skip given what you have. There's a reason you wanted to be on a no-buy. New products are launched all the time and you will be continuously tempted by the latest and greatest. If you really don't want to buy more gloss, I'd suggest not setting yourself up by trying them on. That's almost certain to trigger you to purchase.
Could you be satisfied buying one? Some people are, but others just want more when they get a taste. If you can just enjoy one, get the one you like best. If having one will just make you want the other six, then walk away. There's no shortage of collections and formulas coming and you have heaps to get through.
