For all the FBM sellers out there, I found a great source for third party shipping.
I was constantly comparing shipping prices on Amazon Buy Shipping to Shippo, Easyship, Pirateship and shipstation.
I have to do this because I do not ship enough to get any attention or real discounts from UPS directly.
Unishippers is a great company for other seller like me.
They are a high volume UPS reseller and can take advantage of different shipping discounts offered by UPS.
They actually set me up with two accounts; one offered discounts for large packages (over 48") and the other gave me discounts on smaller packages.
I use Veeqo to integrate all my ecommerce and I was able to enter these two account numbers into Veeqo as "Shipping Carriers"
Now I have one place to go for all my orders and best shipping rates.
The Veeqo and Unishippers combo is a winning combination for me.
BTW, Unishippers has excellent customer service and they actually pick up the phone and work with you.
