Sponsored listings showing at the bottom of the page, not the top anymore?

Hey everyone, like many others I have noticed a massive drop in sales over the last couple of weeks.

I checked my sponsored listings yesterday and even though my Keyword bid per click is high, my listings are still showing at the bottom of the page, not the top like they did before?

Has anyone else had a similar issue as i feel like i’m pouring money down the drain at the moment!

Sale are up , question whats is the product and you can expect lots of people will be advertising around this time of year
