This is a really good idea. You just need to have a source of items to sell. Scouting around for cheap items or freebies is the hardest part.
Annoyingly i used to know a website where people would post stuff they were giving away, which would have been useful to then sell on. If I remember it, I shall post it.
Jordan you should just do as I do.
Buy locally from a facebook page, try and get a few purchases organised from the same are all at once so your not driving around buying things to often as you will waist money on time and fuel.
Bring them back home, inflate the price a bit, and put them onto another facebook page.
You will have no more fuel bills etc as you are now the seller and purchaser will come to you.
You will from time to time get someone moaning at you that I saw you buy that from so in so page for £10 and now your selling for £17 but so what ! they arn't paying your bills are they !
Its a nice little was to earn money online and is relatively easy top do.
