Willing to combine shipping for multiple winning auctions. For example, one buyer purchased seven separate 2 or 3 CD lots. Postage individually at $4.13 a pop totaled around $29. When I combined them into one box the postage was $7 for all. So, if you are hesitant to spend $2.99 or $3.99 for an auction because the postage is going to cost more than the CDs - realize I’m happy to combine to save you money on shipping. 

I combine by the week. For example, if you win an auction on a Sunday and let me know that you are bidding on more, I’ll hold off on sending you an official invoice until auctions close the following Saturday (one full week). You have to let me know before you pay, though, because I ship out all the paid auction items the day after payment is received.
