I’m in the Northeast and have good experiences with Smartpak, Dover, Adams, and Riding Warehouse.
Smartpak has been a little slow in getting my autoship supplements to me, like they arrive the day I run out of my supplements, which I’m not crazy about, but it’s whatevs.
I haven’t ordered from Dover in a few months, but they’re always pretty quick for me. Sometimes things arrive before the charge shows up on my CC, it’s wild.
Riding Warehouse is really reliable and used to take longer to ship to me because they’re on the west coast, but they recently opened a warehouse in Georgia, so my last order got here in 2-3 days.
Adams always ships really fast to me. I haven’t ordered from them since they moved to Aiken, but I’d imagine the shipping times won’t change a whole lot.
StateLineTack has always shipped slow for me, even in pre-Covid times. I’ve never had to return anything to them so I have no experience there.
Staffing, supply, and shipping issues are a real struggle for every company, not just horse-related ones. The staff these companies do have aren’t behind just to make your life difficult. Being kind is free.
