Here are the details:
Pre Address and Pre Stamp all Valentine's
Enclose them in a larger 1st Class Envelope and Address them as follows:
Postmaster -Attention Valentine
446 E 29th St
Loveland, CO 80538-9998
The Valentine's need to be received NO LATER THAN February 8th if their destination is somewhere in the US. More details can be found at the Loveland Chamber of Commerce.
I usually send out twice as many Valentine's as Christmas Cards. They are usually homemade but not always. This year I am going the route of semi- homemade. Is that custom? Anyways, send some love this year.
