Tim's prices are below internet pricing most of the time anyways. I just bought five Radium halide bulbs from Tim becasue it was time to replace my old ones. Best internet price I could find was $74 each. Tim sells them for $70 each normal pricing.
But Tim does not ARC discount his drygoods because they are cut down to the bone already. Just so you don't expect 10% off the already low price.
