On Saturday, my wife spotted and I subsequently bought a LionChief Polar Express train set from either Pete Costa orPeter J. Costa, (they had adjacent tables - I believe one may have been the father and the other the son.)
I need to contact them because in our haste getting and paying for the set (the only LionChief PE set he'd brought to the show), the person whom we paid did not write out a receipt for us (although he did write down info on a yellow sticky note which he kept). Later on during the show I noticed that the other gentlemen working at those tables were writing out receipts for sales but I figured they're really busy and didn't bother asking for one then. However, I'm now thinking that with electronic devices being the way they are and prone to possible failures that I should have a receipt for Lionel warranty purposes should the need to use that warranty ever arise.
If you've bought from Costa at a show, (i believe they do business under Town and Country Trains) and have on your receipt a number where I can contact them to get my receipt, please post it here as a Bing search for Peter J. Costa / Pete Costa had no hits while Town and Country Trains did turn up their eBay store but as is the norm for eBay stores, no contact phone number is shown.)
I hope I won't ensue difficulty having them send me a receipt after the fact. Thanks for the help.
