 Most Prices and Discount levels have been reduced recently.  

I'm afraid I will have to disable the Store for a while while I take inventory of my stock.

 

After attending a nearby Hamfest I find that over $2000 worth of parts were stolen, and many parts of which I had 1000 in stock are completely gone. The theft was very selective, some parts in drawers with many others were taken but the rest left alone.

 

Sorry for the inconvenience but this could not have come at a worst time, right now due to the economy I'm barely making it money wise, so replacement of the missing parts is going to take a long time.
