I used to do that until I realized that the system ignores it. Sometimes, you may find the comment still visible on the web version, but it is hard to find, and on the more used mobile version, not found at all. And the price sort totally ignores any comment. You might want to add your thoughts to this thread in the forum: http://www.bostongasprices.com/Forum_MSG.aspx?master=1&category=1056&topic=513029&page_no=1&FAV=N

I don't know what you are looking at or where you are posting prices, BUT there is NO such check box on the web posting page http://www.bostongasprices.com/ReportGasPrices.aspx and there is NO such click box on the iPhone mobile app from Gasprices.com I wish there was and that the viewer could see the indication - but there is none!

dealr, although your observation is correct, your statement violates the policy of GasPrices.com which specifically states that the price to be posted is the lowest cost irrespective of payment method. I agree with you that it is annoying that the gasprices.com report has no means of indicating a cash price v. credit price - and I have repeatedly submitted requests that such a means of reporting be added. However, at the moment their policy remains that the price posted is to be the lowest.
