I received the foliowing email:
"The following bid attempt was placed per your request:

Final price: 77.00
Snipe: 78.16
Status from eBay:
Your bid was too low due to eBay's bid increment system"
I bid 78.16 and my settings are the same, i won a few hours ago auction without a proble. I am using this application for 2 days and already a problem.
Also i want to know after i placed my first snipe for auction number
202049205649 on amount of 36 GBP and shipping 3.40 GBP why i see in Myibidder that my snipe was placed, but too low, at the same time when i open eBay listing page with bidding history i see no my bid for 36 GBP

i set my default time for snipping to 4 sec. and i am using eBay UK site.
Last question - why into download page - free stuff i can not download the app for Opera, nothing happens when i click on it. I tried a few times with disabled add-ons
Regards.

I understood the firs question is answered in other post and here:
https://pages.ebay.co.uk/help/buy/bid-increments.html
I never paid big attention on that.
If someone can answer is the application for Opera only for the downloaded Myibidder software, or may be is only for Opera v. 11 and v.12, because i need this app but can not install it?

I will be happy if it have an option to edit my thread, but i can not see, that is why i replied 2 times.

I believe the most recent Opera versions support Chrome extensions, so you can use the following to install it:

And yes about the bid increment. You got it right.
As a suggestion, I usually add 1-2 bid increments over my maximum amount to cover it.
If the listing is kinda important, I may add 3-4 bid increments.
