templatemonster template monster bait and switch on checkout, Internet

I visited this site looking at a template, and after seeing one I liked I added it to my cart, there was a crossed out price on the site and in red a discounted price. $48.00 I then went looking at other sites and left the tab open with my shopping cart, I clicked checkout and my template price went from  $64.00 $58.00  to  $64.00 $60.00 Then I opened a support chat and they asked for my link then the price went to just $64.00

After speaking with support they apologized and said I would have to email someone, then I told them how furious I was and they simply thanked me.  This company uses some kind of weblogic to change prices while your checking out, I feel it is deceptive and falsely advertises the product, this is obviously a vendor who assumes you are not paying attention during your purchasing experience.
