We received an idea that we would like to put out there. We heard that UPS or Fed Ex might help us with delivery. If anyone knows of how we can get help in this way, please EMail us.
 Another thought, the best way to package keys. Small amounts could be wrapped in paper and taped. Large amounts might be best wrapped in newspaper and boxed. What do you think?
We have received some keys in envelopes in which the keys cut through the envelope and were lost. Please tape or wrap them so as they do not fall out, Thanks.
I hear from others that it may be about $1.50 to mail 15 to 20 keys? Lets hear from others. 

O.K, since this is all new, we have found there might be a problem with the mailing of many keys. The cost of postage is the main one. If anyone has an idea of an easy and affordable way we can all do this, we would love to hear it. We are not sure what, say 50 keys would cost to mail. We will find out and post it here and see if its cost effective. If you do not mind the postage, we thank you again.

If you have a bunch of keys and want to help, maybe you can get a bucket and collect more keys and if you are in the tri-state area, we can figure out a way to pick them up.  Hopefully we can figure this out. Thanks
