Thanks Vitolo, I'll try to salvage the dimmer switch this way.
Classical whiny service desk experience story below:
I know you catch more flies with sugar. But it seems that the guy is overworked, or something. When I first contacted him about the oddly shaped heater cover, he suggested that the ceramic element was out of place. Then he suspected the dimmer switch to be broken, and wanted me to send in the unit for repair. Due to the price and risk of sending a vaporizer through two customs... I decided to try another approach. So I asked him if I could get the instructions and the part for the repair sent to me. Sure thing, it would cost me $69 to have it shipped to me. Since I was in the market for some accessories, I suggested that I make an order for the accessories and he include the part in the shipment. Chris agreed to this, and told me to send him the order number, so he could charge me for the part through paypal. After sending in the order number to him (Which was paid in full with CC), Chris proceeds to send me a paypal request for $140.... When I asked him why he is charging so much, he just replied that the part (which would be replaced for free if I sent in the unit) cost $25, but offered no explanation to why he requested $140 extra from me to to include the part in the shipment. At this point I asked him to just cancel the order and forget about it.
