My local Salvo's and Vinnies are atrocious for prices. Salvo's are no longer not for profit so try to make as much profit as they can. Also the people who work in the shop aren't volunteers any more like the old days, they have to be paid. A few might still be volunteers, but most aren't. I won't step in there any more because the prices are ridiculous. As mentioned, you can get brand new for cheaper usually.

The local (I think) Uniting op shop is great. Their stuff is fairly priced. The put their prices fair as they want to encourage the needy to come in and buy from there. They know the (true) needy can no longer afford to shop at Salvo's or Vinnies. Like someone else mentioned, on the occasion I do buy something from in there, I always give extra because they do a fantastic job.

The volunteers do a fabulous job keeping the shop spotlessly clean and everything is ordered, not like the other place where everything is just dumped in boxes or crates for people to rat through. All the clothes are in the correct sizes, they'll have summer and winter separate, they'll often have the same colours altogether too, so if you were searching for say a pink dress, you could go straight to the pink section and not spend hours scouring over everything.
