Did you know there was such a thing? It's all about the details. I recently received two packages over the last couple weeks, both from the same supplier. My wife noticed the first one then upon receiving the second I looked to see if it was there as well. Yes, Viper postage stamps on both orders. Does the shipping get there any faster? No Do they cost any less? Nope Is it worth the extra effort to purchase these and use them in our hobby? Yes it is! Many times customer service is so efficient it goes un-noticed, often it also goes un-thanked. Sad. I had no idea there was such a postage stamp, but I am excited there is, and I am going to look to purchase some of these as well. For the effort to use these stamps and everything you do for the Viper community, Thanks Jon.
