I've noticed that my shop discount is no longer 20%. I have a 15% buff from who knows where that expires in about 5 hours. But the item in my inventory is doing nothing now.

Item seems to be working again, but stacking in a really bizarre way? It might be taking 20% off, then the 15% off buff from some unknown source.

It is for me...

I tested it by just now buying "Blue Casual Button Down"

List price in shop- 2278. Final purchase price- 1549. It's only 68% of the list price.

If I had only gotten the 15% buff, the price would've been 1937sP. (And I double checked to make sure it took the right amount of sP from what I have available)

Now I seem to be getting a double discount as well. Guess this can be locked.
