Propane bottle out of date 12 years old. April 03, 2014, 12:45:42 pm Yahoo Message Number: 145592Here in Denver Wal-Mart is running a propane special. The exchange price for a full one is $18.92. They are having a special of $18.92 and you also get a free gift card for $10.00 The refilled bottle price is then $8.92. This is a good chance to get rid of that outdated bottle that is 12 years old and needs to be inspected. The exchange bottle that I got has a date of 4/2013. The bottle that I gave them had a date of 3/2000. I just look at the bottles for one that looks like new and check the date. Pick one that has a new date. The person that is giving you the bottle does not care. Check your local stores.
