Pros: excellent customer service, wide selection of porducts, low shipping
I recently started using Chewy.com to buy my cats hairball remedy as well as her dry cat food. My cat, Angie will only use 1 specific brand of hairball remedy, and its hard to find in the pet stores where I live. I was thrilled when I found it at Chewy.com. It was very inexpensive and as I browsed more on the website, I found all sorts of stuff my cat uses that was considerably cheaper than the local pet and feed stores. I started getting my cats pet food (Stella & Chewy's and I & Love & You) from here because its so much cheaper, and you can set it up to be delivered every month at the same time, so you don't run out. Plus, shipping is super cheap and if you spend more than $50.00, its free. I also like their selection of cat toys, way better than most online pet stores.
Pros: fast shipping; great everyday prices; no sales tax in most states
I am always impressed by the speed of Chewy.com's shipping! There have been times when I placed an order in the afternoon and received the items the next day.
Their prices are also very reasonable and fair. I think that Amazon.com tracks some of the prices at Chewy.com and matches them. A big plus for Chewy.com is that you don't pay sales tax in most states!
They also occasionally send out coupons through snail mail. I've received a postcard with a one-time-use coupon code for $15 off $49+, which is crazy awesome when stacked upon their already-great prices.
