Very dissapointed in their response to groupon... my two cups of yougurt I purchased came to just over $12. I provided my $10 groupon and paid the difference which was an additional $3.15 after tax. Upon returning home, I looked at receipt and saw for some reason they only gave a credit of $9.15 for the Groupon instead of $10. Why I do not know. While only a difference of .85 cents, it is the principal of the matter, and because of such, I and my family will not return and I will advise others to find a different yogurt shop that is more honest. Paying $5 for a $10 groupon means I should get a 5$ Groupon benefit. When i get jipped out of almost $1 of the extra $5 Groupon benefit, I feel like I was screwed by almost 20%.. In this economy, companies who do such unethical manuvers will not survive, and I will now spread the word in the company I work, that has 1800 employees on sitem and is located less than a half mile from this yogurt shop. I may not be able to tell others which store to go for yogurt, but I will know where to tell them which stores not to go. .
