Double a fiver

We are challenging you to take 5$, 5€, 5£ or the equivalent of a fiver in your local currency and purchase something that could be later sold on a profit!

We know that this is tough and if we could do it instantly we would all be gazilionairs, but consider spending a moment to think about a creative way to double your money.

We are looking for great ideas, so please do not offer fraudulent activities involving stupid schemes.

Simple example: purchase a pack of cold water and sell it to the jogging people at the park!
