Purchase the bundle now. Between February and April I will be adding over 20 games. By buying now, you are purchasing the bundle at the lowest possible price. You will just need to simply re-download the bundle every time I add new games.
I've personally purchased growing bundles before and I love how much money I've saved. By the time the bundle is completed, it's value will be $40.
It's also on SALE for the TpT inspire sale.
