eBay is a good source of chips or parts to buy.
But some Arduino users from countries not as developed as USA, Canada, Great Britain, ... find it more difficult to buy outside.
I have read opinions in this forum that If you do not have an international credit card, you can not buy through eBay.
I think I have good news for members of this countries, and I will try a brief explain, but I suggest to other members to add insertions to the topic to make them usefull for users of this "far" countries.
eBay has a child company called PayPal.
If you have an account in PayPal you can easily buy through eBay ALMOST any ITEM, almost in ANY EXTERNAL COUNTRY.
This is only a part of what you can do with PayPal, because you can also RECEIVE money from any payer of virtually any external country of the world.
Some years ago the only way to have an account in PayPal (AND TO BE ABLE TO PAY WITH IT) was through a credit card.
I never used this because I personally hate credit cards , because of the problems they can give you, so NEVER USED PAYPAL.
But recently an interesting innovation has arrived to PayPal: YOU CAN PASS MONEY FROM YOUR BANK ACCOUNT TO PAYPAL WITHOUT A CREDIT CARD, through a bank transfer.
Once the money is in your PayPal account you can buy at pleassure
I actually use this method and I can say only good things , with just 1 exception >
From the day you order the bank transfer till the day the money is in PayPal, usually 3 weeks have to pass.
After just 3 day money dissapears from your bank account, but you can ask money back to your bank to break operation. So PayPal waits until break operation time expires to pass finally the money to your PayPal accout.
This rule depends on country and bank rules but is a good approach.
I suggest a good policy to have 20 or 30 dollar always in a PayPal acount, BUT NEVER BIG QUANTITIES.
Because you operate PayPal esentially with your eMail address, and hackers >
risk is always there. Also any one 8-) who can enter in your eMail can SEND your PayPal account money to OTHER destiny :'( .
20 or 30 dollar do not interest much hackers, but is a good quantity to buy electronic devices in eBay ;D. or kits to Arduino providers that allow you to pay them by PayPal and ship to your country.
PayPal has succeeded until the point that external companies not related with eBay, also allow you to pay them by PayPal.
There are more bennefits and problems, but more expertice opinions will be welcome to this topic.
