Here is a tip from Jay Eichler, owner of The Ultimate Thomas Store, http://www.ultimatethomas.com, that he say “exploded his sales in the last year.”
“Up to last year, I was a seller on eBay (and via my own website) which shipped most of my orders (under 3 lbs) via USPS. I would use their website (usps.com) to generate the labels and ship via Priority Mail. The shipping labels I purchased especially to print in the dimensions required by Click-N-Ship (or PayPal shipping, for those that use it).
I decided late in 2009 to upgrade my entire shipping station and purchase a thermal printer (purchased reconditioned off of eBay for ¼ of it’s “new” price) to print my labels. In addition, I upgraded to a USPS-approved shipping service (in my case, Endicia), which then allowed me to offer First Class shipping of my items which could ship for under 13 ounces. Yes, this would mean that I would not be able to use the “free” shipping supplies offered by the USPS for Priority Mail shipping, but I soon realized that the boost in sales my items would get would far outweigh the benefit of the free supplies.
The result of this combination of changing shipping service methods, as well as the thermal printer (which you can get labels for free if you have and use a FedEx or UPS account) has resulted in a surge in sales due to the lower prices I can offer. While I am paying for the Endicia service ($15.95/month), my costs are still lower due to the free labels and since I use a thermal printer, no use of printer toner.
I’ve said it before, and I’ll say it again…this was the best thing I’ve ever implemented to help my business.”
To provide you an example of the savings, I looked up how much it would be to ship a 12 ounce package from New York to Beverly Hills. As you can see below, a First-Class Package is $3.09 compared to Priority Mail with the online discount of $5.44. The savings is 43% which is HUGE for an eBay seller. Thank you Jay!
