Current bid is $10.00, my snipe at $30.00. What will happen?
This is very important question - that's why I've created this new topic.
Here are the two opinions:

1. FAQ (https://www.myibidder.com/login/faq/4/#q7) explains that myibidder will bid the lowest available amount (one eBay bid increment more than the person before you). So if the current bid is $10.00 myibidder will bid $10.50.
In my opinion this is the good behavior.

2. In the thread http://www.myibidder.com/forums/viewtopic/5229/snipe-malfunction/ Sashka mentioned that myibidder will always bid exactly the amount I set. This means that myibidder will bid $30.00. Three times more! And this is how myibidder really works now.
In my opinion this is the weird behavior.

The question is - what is the right behavior? How myibidder should work?

1. It did not say it will bit the lowest available amount. Please read the FAQ you mentioned.
Myibidder will work the way as I explained in the topic you mentioned in #2.
Please check it.

Could you please explain the answer from FAQ?
Below I've commented the answer as I understand it, please correct me.

If your snipe is higher (amount set = $30) that current bid ($10) then you will pay only one eBay bid increment more than the person before you.
That means if current maximum bid is $10.00 then you will pay $10.00 + $0.50 = $10.50 only. (How will I pay $10.50 if Myibidder bids $30?)

How will I pay $10.50 if Myibidder bids $30?

That's called eBay proxy bidding. That's how eBay works under the hood.

Now I've caught it. Thank you very much.
