I found a donation machine in a shop.

DONATION

What does it do apart from take my money, if anything? I noticed it seems to break after a few coins.

  • It stacks over multiple runs. So far I'm over 200 coins and stuff keeps unlocking regularly. – shanodin Nov 7 '14 at 13:35

Edmund explains it here, basically it slowly upgrades the store, sort of leveling it up to have more items, etc.

  • I forget what amount of coins got me my first shop upgrade, but it's 100 (total) coins for the 2nd one. – Fambida Nov 5 '14 at 16:05
  • @Fambida It's 20 coins for the first shop upgrade. – Powerlord Nov 7 '14 at 15:05

In addition to upgrading the shop, you can also use a bomb on it to get some coins out of the donated money pool. Especially useful if you only need a few coins to buy that shop item.

It seems that using a bomb "destroys" some coins

    "Especially useful if you are only need a few coins to buy that shop upgrade." ...no it isn't, as the amount of coins in the donation machine goes down every time you bomb it. If you have 18 coins and bomb it to get 3 coins, putting those 3 coins back in... will bring it back up to 18 because it dropped to 15 when you bombed it. Or did you mean "shop item" instead of upgrade? – Powerlord Nov 7 '14 at 15:07
  • @Powerlord - Yeah, excuse me, I meant shop item. Fixed it. Thanks for pointing that out. – 5pike Nov 7 '14 at 17:11
  • You can however abuse the donating if you have Humbling bundle, as the coins dropped by bombing the machine will be doubled. – Malco Dec 4 '17 at 19:58

I noticed that the number of coins donated remains from run to run, and when it reached 10 I got the secret "The Blue Map has Appeared in the Basement!" Hopefully this helps.

  • It carries between runs. That is an important feature because some items require over 200 cents, and the thing jams (maybe for the rest of the run) after putting in a random amount of money. – Shadow Z. Jan 15 '15 at 18:45
