Welcome to NStamps! (known as Noernberg Stamps elsewhere). I offer Worldwide Stamps, mostly as singles, at reasonable prices! I don't sell much on feeBay, but I have a 100% positive feedback of over 18,000 on HipStamp, so buy with confidence! APS member #209752.
Regarding Shipping: You may have noticed that the Shipping setups on Unisquare aren't as robust as one might like. To that end, I have been forced to have the default shipping reflect the more expensive international shipments to ensure I'm not underpaid. If you are in the US and get charged the higher rate, worry not! I can either (a) invoice you separately upon request, or (b) simply refund your overpayment in Paypal. Sorry for the trouble!
A note about the "Star" ratings in my description: I have established my own "grading scale" for the quality of stamps ranging from 0stars (spacefillers) to 5stars (very high quality and near-perfect VF or better centering). Most are somewhere in between. If you want to limit your shopping by this nstamps grade, simply search for the grade level you want to restrict the store to. Highest quality? Search for "4stars" or "5stars". Looking for deals and faults are ok for you? Look at "0stars" and "1stars". This is intended to help you target what you are looking for, and perhaps not waste your time looking at things that don't interest you.
