Not really an AIBU but I need some MN help and this is the only section I use. 
So my family and I are doing a competition between us. We each have £10 as a starting float and a month to make as much money from the starting £10 as possible. The winner gets all of the money earned. (There is only 5 of us doing it so probably not going to be millions!)
Can any of you give me some suggestions?
So far I have thought about buying some bits from eBay and reselling them and maybe a trip to the charity shop for some brand named clothes but quite honestly I’m not sure that’s going to cut it!
I can’t do anything too time consuming as I have animals, job, family, etc etc and I’m middling intelligence so I’m not going to be able to work out a complicated mathematical betting system.
I’m hoping you might give me some amazing ideas as my DH is already gloating that he is bound to win 🙄
Please help me out MN’ers!
