I usually ship items within 24 hours some items might take a little longer so you should expect your item within 2-10 business days to be delivered, my shipping prices include packaging, boxes, materials, gas, ink, time, and insurance if the item is over a certain price. I always email tracking numbers and post them on eBay at time of shipment. 

Feedback is automatically left after feedback is left for me; I have my eBay system setup to leave feedback automatically after it is left for me. 

I will allow returns under the following conditions: If there is a problem with item the buyer must contact me 30 days after item has been received by buyer. I sell new and used parts please look over descriptions and pictures before bidding. 

I do my best to keep the shipping costs close to actual cost, unfortunately shipping prices go up at least once a year, this hurts all of us but it is something we have to accept when we purchase products online. I do cover materials and handling in my shipping cost as well it cost a lot to sell on the internet these days. 

I am not always at the computer sometimes I need a few days to respond to questions especially over the weekends I am not always by the computer on the weekends, remember it is just me selling all of these items.
