We're in the low-buy thread for a reason - because we wanted to be more thoughtful and deliberate about our purchases. That doesn't mean no-buy, it just means no more 'buy all the new shiny'! I think most of us are trying to only buy items we love because we already have more than enough. While there may be quite a few nice items in many collections, it doesn't follow that we need to get them all.
If there are a couple you'd love and want, great. But just because someone else buys all the lippies and l/g it doesn't mean that they're 'must haves' and that we have to follow suit. Maybe others don't have the base of makeup we do. Maybe they're just starting out. Or maybe they'll be here in a few months when they realize that they're purchasing in a less measured way than they should. Either way,
just because they're jumping off the bridge doesn't mean you have to. (Had to insert that - I'm a mother).
