Problem or limitation

It'd be nice if smart spawner add support for ultimateshop, since this as something called dynamic shops i can't really set a constant item values so it does requires something on smart spawner itself to make this work i suppose

Proposed solution

Integrate ultimateshop to smart spawner

Use case

@IndrajeethY SmartSpawner doesn't currently support dynamic pricing, even when integrated with UltimateShop
