hey maria, I have used ebay, and sold a lot of bub's clothes that way. It was really easy to set up and I made a reasonable profit. Also I have found quite a few bargains on ebay as well. Sometimes you can pick up bulk buys that have a range of sizes for fast growing bubs. It's worth checking out if you have time. Beware though it can be addictive scrolling through all the items listed because they all look so good and you want to buy them all especially if they are a bargain. I try to set myself a limit per month and not go over it. On the other hand, I have also saved a lot of Neishas' things that she looked really cute in or were gifts from special people, and of course the knitted things that you get are never parted with ( these were things that I wore 30 yrs ago that my mum saved!!!) If packed correctly they never go off. I've had two children in them. I generally pack them in freezer bags with a lavender sachet (not touching clothes) and all the air pushed out and sealed. Then all the bags go into a big plastic box that can be sealed and stored in the top of my cupboard. For 30 years old some of the things looked brand new!
best of luck , Annie
