Why is it that when I reseached the possiblity of a postal rate hike I couldn't find anything on it, that is until hours after I purchased all the stamps for my invitations and save-the-dates!? Of course the USPS will not take the stamps back but will be happy to sell me two cent stamps to pair with them. So either I can send out invitations to my April wedding in December or have additional postage tacked on via the two cent stamp in February (sending out the invitation as orginially planned). So the question is how tacky would the additional postage look? And do people really notice the postage?
