tolltag.ie savings

Useful post on the new M50 toll charges here, but figuring out the cheapest option for casual users may be a little more complicated than you might think. The table below shows how much you'd save or be out of pocket using a tolltag.ie tag for the first 113 times you use the new tolling system... If you see yourself using the M50 less than 80 or so times in the next few years, you might be best going for the video system...

Red means tolltag is more expensive or the same cost (for that many trips), green means tolltag is cheaper.
