I didn't really get what you were trying to say.
With 25$ you get:
125k TC.
One or more items from shop/market. The total worth of the items should max be 150k. The worth is counted as prices the items in dealfinder.
An example:
You want pure force.
Found: Pure Force for 30,000 tc -1900.00% off
You also want pure relax.
Found: Pure Relax for 20,000 tc -1233.33% off
The total worth of the items is 50k. You want to get the best deal you can get so you keep adding items on for it to be so close 150k as possible.
