My Favorite Mail Order Pet Supply Companies

Ryan's Pet Supplies
PROS: low prices, great selection, and prompt service.
CON: High shipping costs


Jeffers Pets
PROS: Decent prices, has unique items, prompt service
CONS: Haven't discovered any yet.

Karen Pryor Clickertraining Store
PROS: Low prices on some items, decent selection
CONS: Absolutely no customer service support, some products are not well made.


Petsmart
PROS: Large Selection and low shipping charges
CONS: Some items are over-priced and others are not well-made

Smartpak Canine
PROS: Great selection of non-frou-frou dog coats, competitive prices, option to order dog food portioned out for your dog's daily meals, complete with any supplements you may feed
CON: Ordering from Smartpak Canine gets you on the Smartpak Equine mailing list, leading to unwanted catalogues full of horse gear

Amazon
PROS: Wide variety of all things dog may be available through Amazon, including some hard to find items and free shipping for orders over $25.
CONS: Some items are sold through third-party companies; shipping on these items may not be as reliable as purchases shipped directly from Amazon and do not count toward free shipping.

Pet Flow
PROS: Wide variety of food, treats and other items for dogs and cats, including premium treats and foods that may not be available in some areas. In my experience, prices on items I order are comparable with local stores. Deliveries are made via Fed-Ex, so no dragging 30-pound bags of dog food from the car into the house. Free shipping, once a minimum order amount is reached. Automatic reorders, which make it hard to run out of necessities.
CONS: They do not charge Ohio sales tax; this is one more item to keep track of for tax returns.
