If I were interested in the purchase of test equipment or anything else for that matter then chances are that I would already have sourced a copy of the relevant information or reference documentation, just out of habit I rarely if ever use links provided by Ebay sellers and prefer to seek this type of information out on my own, reference information relative to a specific device such as calibration data sheets or original purchase receipts could be an annoyance as previously mentioned.
Yesterday whilst browsing the camera section I noticed one listing which showed an image of a memory card which had been placed on a sheet of paper and the sellers phone number written below it, on Saturday I went on a mission to find particular sized storage containers and finally found what I was after on Ebay, I then searched on Google for the sellers name and it turned out they have not only a dedicated web site with all of their contact details but also a warehouse only ten minutes north of me, I rang them then went around that afternoon and bought eight great containers and ordered another dozen, I could easily post a picture of the purchase but that might give the game away, true story and I couldn't believe my luck.
