I encourage multiple purchases. I will happily combine purchases under the following conditions: 1. I will combine purchases to include all that are won within a seven day period from the first purchase as long as I have been notified by the bidder by email (from his eBay registered email address) of his intent to bid on more items within the same seven day period. 2. I will delay my emailed invoice for seven days from the first purchase in the event that the bidder is maintaining an active bid on a currently running auction. 3. I may extend the period in which you combine items at my discretion. I will not extend this courtesy if you fail to contact me or ignore my messages. 4. Articles of different formats may not be combined. (Open Reels and LPs don’t ship well together.) In short, I will happily allow you to run a 'tab', but not on indefinite terms, nor without my approval under the terms stated above. New purchases that are made outside of these parameters will be charged the same shipping charges as a new transaction.
