I usually purchase Fancy Feast from Target or PetSmart. You have to shop the sales and use coupons to get a decent price on most foods.
Unfortunately it doesn't! I checked the prices on Amazon and Chewy's. On amazon, sheba has a subscribe and save option whichmakes it cheaper and chewys has a sheba discount as well. FF doesnt qualify for subscribe and save or the chewy discount.
Also, you can try mixing some Sheba into the Wellness and gradually increase the amount of Sheba.
