I like that it provides all of my customers with their information so they can use them right away or in future visits! It's also easy enought for those who aren't technically savvy to put together an effective list of codes/special offers and email out to users at once.
One thing we've noticed is when looking up our data from past events (as well as current) sometimes there are discrepancies between what other providers say vs how ours looks to be entered into online - this seems minor but could prove costly if something were wrong? As always check everything twice before submitting because things seem fine one minute then get changed midstream which has been painful since some dates don’t change until after submission occurs due to lag times.
