arcade and more. Selling a broad range of new old stock and used

All items ship from zip 61761 U.S.A. While most of my listings feature
1 business day turn time, I'll always try to make it same-day
shipping! Monday-Friday orders placed by 10 a.m. CST will usually make
it to the Post Office same day. Monday-Friday orders placed after 10
a.m. CST may not get to the PO until the next day. My ultimate goal is
to have all orders to the post office by the next business day.
Saturday/Sunday orders will be posted the following Monday. Postal
Packing: I pack very carefully to avoid shipping damage, using the best box to protect your item from damage, while minimizing your shipping cost. I love to use bubble wrap and so far have not had a single item damaged in shipping. Check out my response; there are many mentioning shipping speed and good packaging. Will always try to use recycled options whenever available but I do maintain an inventory of fresh, recyclable boxes so I'm not wasting your and my time digging around the house for an old box to ship your valuable audiophile tube!
