Matt has helped me in many a transaction, just a fantastic and helpful person. Got some very hard to get cards through him, and I always add a few dollars more for his time and effort and bought him an auto card from his wantlist for his troubles. I'll go on record and say that I strongly believe that anyone receiving help from Matt should reward his efforts by the same token, as he has to go through a lot of trouble for something that he needn't have to do.
To save Matt the hassle of staying up or remembering to bid on the item, I personally bid on the items after contacting the seller and explaining the situation.
If they accept international Paypal, I pay for it myself and get them to ship it to him, otherwise I transfer it to his US verified account and he transfers it to the sellers account. In that way, I try to minimise the amount of work he has to do and I would urge others to do the same.
