I have been using Chewy for years. I have a number of items on Autoship and it is very easy to adjust the delivery date and add/subtract from those items. I always get a notice that the Autoship is coming up and the deliveries are always on time. I find their prices to be very competitive. A recent transaction prompts me to write about their stellar customer service. I bought a $90 bag of dog food. Before I had even opened it, our vet recommended changing the food because of a skin issue. Without hesitation, Chewy refunded my money and told me to donate the food to a local animal shelter. Love that philosophy!
