Hey guys, this is a really interesting idea! One question - i'm new to the wtb concept, and i'm not a member of any facebook groups so i'm curious as to why someone would post a wtb instead of shopping around online?
1. Items you cant find anywhere - they may be rare or in limited quantities such as a pair of Nike Air Mag sneakers. In this case you'll be better placed to find your ideal product.
2. When you don't know exactly what product you want - people create 'want to buys' for generic items e.g. 'a black trucker hat'. This way, wtb posts can actually aid product discovery and make the whole shopping experience easier and less effort since sellers are coming to you and not the other way round!
Thanks!
But in these Facebook Groups, general 'want to buy' posts are created since there may be a brand/item that you don't know about - someone else may have found something that fits the criteria in the past.
This is a way for people to recommend items to you, tapping into their experiences & learnings and a great way for you to discover new products without the effort of trawling google/eBay/Amazon etc.
