Greeting Cards and Envelopes (Universal City)

Looking for packs or stacks of unwanted greeting cards or envelopes that are roughly 5" x 7". I use them to mail out vintage postcards I sell, so open packs are ok, used are ok, damaged might even be ok. Printing on the envelopes is fine, as I cover the envelopes with a postal label. Thanks!
Can you help with this request?
