When you see a light for sale and then a little voice says you’ve owned that light before. Then you check your sales/email/shipment archives and realize you’ve owned it twice before, modified them, and sold them. You go back to the sale page, thinking if it might be different this time, maybe a different modification? Some time has passed since the last ownership and maybe life’s needs have become better suited to it now? Or— Oh! one of your own sales went though, so there’s extra cash and you buy the light for a third time.
