I prefer Paypal, but will also accept money orders and cashier's checks. When more than one item is purchased on auction or from my store inventory, you will receive a shipping discount based on the total weight of your items.
Generally, I ship once, sometimes twice a week. I will inform you if I believe your shipment will be delayed. Even though I normally don't specify overnight shipping, many times I am able to accommodate such request. Please contact me if you're interested in an item and want it shipped quickly.
