Ladies, ladies, ladies........please make sure you read this!!!! I went to the PO today to check out the 'skinny' on increased price for flat rate envelope. As of January 2, the price for the FRE DID increase to $4.95. I asked about a stamp, and was told there IS a $4.95 stamp for this. Please make sure your return addressed FRE has the correct postage stamp! I love what is being posted. These blocks make me drool!
