Here's a piece of advice that I would tell you to consider strongly - and no offense to our Canadian members here, so please don't take this the wrong way.
When you sell an EXPENSIVE item (to me, electronics or anything greater than $50).. don't sell to anyone except those in the states. I have had 2 occasions where I was burned in one, but was smart the second time around. Here's what happened....
I put a friends XBox on my eBay account 5 years ago - and this was with a ton of games. He wanted $200, but I told him I could get more for it on eBay and offered to sell it for him. Well, it ended up selling with "Buy it Now" (this is an option I'll use and put an outrageous price on to get buyers who want it to buy on impulse). Well, I had it listed for $450 with free shipping, or they could wait til the auction was over and pay actual shipping charges. Well, the first night I had it listed, a guy emailed me and asked if I'd sell it to him because he was in Canada. I told him no problem, that when he paid and it posted to my PayPal account, I'd send it out. Well he did it right when the auction ended and the next day I shipped it. I gave my buddy the money ($400, because I kept $50) and all was good. One week later, I checked my Paypal account, and instead of my current funds showing $0.00, it showed $-450. I contacted Paypal and they said the item was paid for with a stolen credit card. To make matters worse, since the buyer was out of the states, they had no authority in going after the crook. Needless to say, I was out $400 because I didn't know the "rules."
Again, I mean this in no harm to our foreign friends - I know you guys would never do this... but I think everyone should be aware of what happens sometimes.
On the second occasion, I was selling my JL Audio Amp which was worth about $600 at the time. I put it on eBay and listed it as Buy it Now for $900. I should have known when something was up because the guy sent me an email asking could I send it to his church because he was there doing a mission trip. I said sure (This time I'm wise to the idea)... He paid, but this time I waited a week before sending it out. Sure enough, 1 week to the day I sold it I was contacted by Paypal that the buyer had used a stolen credit card.
So if you're a seller - here are my words of wisdom.
1. Only sell to members on eBay with a CONFIRMED ADDRESS - and ONLY SEND TO THAT CONFIRMED ADDRESS.
2. Only sell to members in the 48 states. You can sell to HI and AK, but make sure you know what it's going to cost to ship it there before hand... sometimes those prices are more than the item is worth.
3. If the buyer uses an unconfirmed shipping address, wait atleast 2 weeks before sending the item - take my word, PayPal will debit your account, and the only way to use paypal for any of your purchases is to make the negative number they give you a postitive, then you have to pay on top of that. So I wanted to buy a $30 flashlight, but I first had to pay $450 to get to $0, then another $30 for the flashlight.
