Gardens Oy Vey
I am using Ordoro, after trying them last year for a while and than dropping them, have found them now to be a great shipping channel.
I sell on my web site, Amazon, eBay, Etsy and hopefully have some sales this year on Shopify.
Ordoro collects all but my web site, which I enter manually.
Than I can pick between USPS (which runs via Endicia), UPS or Fedex. Whoever is cheapest gets the shipment, great for me, as some shipments are 2-3 pound some 30 pound. (I ship live plants).
Very happy with Ordoro. I save more than the $25 a month fee easy in the spring, summer and fall.
