What I am talking about here, is promotional marketing using valid / real postage stamps or use of stamps in general for personal or business usages.
PC Postage Service offers people an easier solution to posting material. It allows you, with an internet connection, to digitally print postal stamps right in the convenience of your own home/office without the hassle of going to a post office. It claims to be around 80% cheaper for businesses who post in bulk and all mail can be easily tracked.
The PhotoStamps is according to me, unique! This feature allows its users to upload they favorite photos, graphics of company logos onto the site. They can also save them for future purchases. There they can edit them (by zooming, cropping, rotating and adding borders) to create professional looking, high-quality, adhesive-backed postage stamps, which I should add, is totally approved by the U.S. Postal Service.This is especially useful for small businesses or offices who want to promote any new products or services in an off-beat manner.
This service however, is limited to postage within the US alone and not international.
