How to pay for things online using BTC?...

[killinitsoftly]

When prompted with a BUY NOW page, indicating 0.1 BTC are to be sent to whatever address... how do you proceed?
Do you send 0.1 + transaction fee, or 0.999 BTC?
Will the retailer fuss over a transaction fee amount missing?

Thanks for help.  Online transaction noob here...

You send 0.1 to the retailer.  That is the payment to them.  Then, if your transaction requires a transaction fee, you include that as well.

Will the retailer fuss over a transaction fee amount missing?

Most retailers use automated software that is looking for a specific payment.  If you don't send the correct amount, the software won't recognize it as being "paid in full".

Most retailers use automated software that is looking for a specific payment.  If you don't send the correct amount, the software won't recognize it as being "paid in full".

Most merchant woftware creates a new address at the checkout and waits until the total confirmed amount received at this address is at least as big as the cost of the order. Sending 0.0999 would just make the merchant wait until you send another 0.01.

But please note! you said 0.999 (rather than 0.0999), which is way more than the order amount you typed as 0.1!

You don't want to do this mistake. I did it one time (I sent a hundred times a very small order amount) but the merchant sent the excess amount back without causing any problems.

Yes i think you send 0.1 BTC + transaction fee. If the product costs 0.1 BTC you can't pay lower.
