Quick note on shipping.
We package everything in card board boxes. We make sure there is at least 3 inches of space between the product and the edge of the box. We make sure the fill material is of quality and will protect your item from poor shipping practices. In large heavier items over 20 pounds we double box the item. So shipping may appear high. These are the reasons why. We charge exact shipping. We do not profit. So if the postal carrier you choose charges us $x than we charge you $x. No gimmicks or tricks here. We have been selling on ebay for years and make sure to read our feedback to see the types of items we sell and see our happy customers.
What we will not do for you.Under size our packaging so you can save a buck and chance having the item you buy from us potentially damaged in transport to you.
What we will do for you.Make sure your item is nearly bullet proof....well maybe not bullet proof but certainly disgruntled postal or courier proof.
We will combine shipping on items if it make sense to do so. Example: If you bought 4 rubics cubes from us yes we will combine, but if you bought 2 large stage speaker enclosures then no. We won't combine as it would exceed limits of UPS or other couriers. We will allow for local pick up if you email us in advance.

That said. If you feel that we are worthy of a negative feedback I encourage you reach out to us first. I am confident that we can make sure you are happy with your purchase from us.
