If i baught 2 Lizard Minion Repellant would i get a 50% chance or will it only be 25% still

Nope, they don't stack. If you buy both the repellent and the trap you'll have a 100% chance, however.

aww dang okay thanks

I don't think it's 100 percent but it is a very high percentage that you will keep the item.

It's not 100%

I have both, and I've missed my items before.
