and if you plan on shopping at a petsmart for supplies, check out the item(s) you want online before you go, then print that page off and bring it in. if there are different size of model options, make sure it shows the price of the exact one you want. all petsmarts will match their own online price and depending on the store some may also match competitor's online prices as well. i think last time i went in i had 2 online prices and a $5 off coupon, saved almost $20. the only catch i've found is that that don't always have the item in the store. then you wait for free shipping online.
