v1.3.1
Bug fix: New destiny cards weren't showing in the new card area.

Additional pack price now scales based on speed. +5% additive per pack per second. Maximum of x5 base cost as pretty sure that's roughly max speed of the script.
v1.2
Updated for 0.48.
v1.1
Now creates a gd file as well as a json file making it simpler to manage saves.
Speed settings updated to per second instead of per 10 seconds.

Locate save file location.
Go to Start > Run

Copy paste this into the run box
%APPDATA%\..\LocalLow\OPNeonGames\Card Shop Simulator

Hit okay.
This folder has your save files.
savedGames_Release0 is the auto save slot and top left in game.
savedGames_Release1 is the top right slot in game.
savedGames_Release2 is the bottom left slot in game.
savedGames_Release3 is the bottom right slot in game.

For the relevant save slot, first rename the corresponding .gd file with something like 'backup'. This will allow us to revert should anything go wrong.

Drag and drop the relevant .json file to this page, or browse to the file manually.

Select the pack(s) required, and how many you want to rip.

Once complete, click save and save/overwrite your savefiles with the two files given.

If anything doesn't work as intended. Restore the backup made earlier.

Select the pack(s) you wish to rip. It will do them in order.

The cost of each pack is displayed beneath its image. Costs are increased by 5% (additive) for every extra pack per second to try and balance this a little - and you'll not be paying shipping.

Type how many times you want to do this, and how many packs to open every per second. At max speed, faster packs mod does around 1.6 packs per second on my computer, but requires you to restock and reshelve after.

Click rip.

On the left, you'll the status of your ripping, with a stop button should you wish to end at any point.

On the right, you'll see the contents of the packs you're ripping.

When you're done, press get save to get the edited save and save it in it's original location.

Note: You can't play the same save you are using this method to rip for. Otherwise, when you load this edited save, whatever you were doing in game will be lost. So exit before using the get save button.
