Unfortunately, I don't mean brushes, fonts and layouts.
I do, however, mean free food, free perfumes, free skin care samples and many more. I order these all the time, and some of them have come in really handy, for example a free BiTE card to get 20% off food at train stations, free sanitary towels, free shampoo, conditioner & shower gel, free teabags, free ulcer treatments, free plasters... you get the point.
The best way to find the good offers is to check out MagicFreebiesUK every day.
These are also worth a mention:
Freegle. Formerly Freecycle, this is the best website to find second hand (or even brand new) items that people just want to get rid of quickly without cluttering up the skip. You can get EVERYTHING on there - furniture, clothes, toys, cutlery... I even saw a car on there once. (followed by about 10 wants posts for cars because they missed it!)
Free2Collect. Similar to Freecycle.
