I currently have Amazon Prime and have started a shopping list on there in anticipation of our new addition next Spring/Summer. I am noticing though, that some things are a lot more expensive on Amazon than on some of the pet supply sites, but then they will charge shipping, whereas I get it included with Prime. So, I am looking for sites that have great prices on food, gear, toys, etc. that don't charge for shipping (or have minimal charges). Any recommendations?
