How do you unlock blank card and also how many store upgrades are there

[Ynd]

The title says it all . I've beaten moms heart like 6 times and I'm on level 2 on the store unlock. Looking for blank card so I can get a greed mode play through to unlock the keeper

[Tato]

Blank Card is unlocked by defeating Isaac as Eden.
There are five levels of the shop afaik.

[Ynd]

Oh okay. Got a pile of eden chances. Any idea the amount of money you have to donate for the shop level to go up each time?

[Arghaab]

It goes up when you get to 20, 100, 200 and 600.

But you can still unlock a few items afterward. The last one is unlocked at 999.

Wow that far huh? I've been putting money in everytime I have a crap run

[Arghaab]

Basicaly, just put all your money in it every time you're on the sixth floor (Mom's floor).

There won't be any shop after that point so keeping your money is pointless.

Donating money in the shop does increase the chances for an angel room to appear, so it doesn't have to be something you do aside from the run you're playing currently in.

There's the shop on blue womb and there are beggers/slot machines you can find or spawn as well as items that work with coins.

Yeah you're totaly right ! I just figured the blue womb wasn't relevant at all to a player with only a few hours in, but I should have mentioned the beggars/machines and the items.

Still, my advice stands ! Donating as much as you can each run is, in my opinion, the best use of your money when you still have a long way to go in order to fill the machine.

I did it the same way, so I'd say you're probably right. I just wanted to point out, that you can do more with coins. Also when you're playing one of the harder characters and having a good run, it just might be more beneficial to keep your coins.
