I have only bought 2 seta of tickets for winter wonderland last winter. I couldn't open the voucher you print so I called. They answered immediately and walked me through opening and printing them
Most. Of the time I have been very happy with the products. I usually look at name and Google it. Ithe usually comes up with info and sales it on amazon.
I have not bought spas or anything like that. I read that they over book and can't get you in right away. I heard sometimes the place is at fault for not limiting the amount they would take.
I'm not sure I would do a trip. For me I would rather do that myself and not stress about it.
Most items are same quality. I ordered 6 canvas prints at Christmas and when I went on site to redeem I was agreeing to receive emails that the company charged for. I wrote the loss off and won't bug those again.
Good luck. Been about 85% or more happy with site

Be careful with Groupon. They do have great deals, sometimes. But, Ive run into trouble using Groupons at others.

Do you mean "Resident or Non-Resident Admission for 2 or 4 at Independdence Lake Blue Heron Bay Spray Park (Up to 47% Off)"? Not 100% sure. In general, I would say Groupon delivers with location deals and restaurant deals. They are just horrible with goods - slow shipping and some of the stuff is real crap and it is difficult to know because the brand name is not provided. But even with location and restaurant deals be sure to read the fine print to make sure that you will use it before the sale value expires. Also, go look for reviews for the particular place in question, google is not very good for place to find a good number of reviews, try trip advisor or something else. You want to see reviews because, it is certainly possible that a groupon is legit but is being offered by a crappy place. I saw one for a Florida hotel, only the address was given. I did a google search on that address. Found out the name of the hotel and found its reviews and overall the reviews for the place were pretty bad. So you have check out reviews for stuff to make sure the quality is likely to be good. Groupon assumes no responsibility for the quality of the company offering the groupon.

The deal is not retrievable in the email they sent me of your question so I can't tell you if that one item is a deal or a ripoff. All I can say is read everything very carefully. I have found that the specific wording of the description can give you lots of information. Notice comments about size, color, etc. You should also google the specific product name and model number to see what other retailers are charging current for that specific item. Groupon sells lots of older or unsuccessful models. Try googling the name mode number and then the word reviews to see what others are saying. Amazon has reviews on just about everything imaginable so you can look the product up there and see prices and reviews. Your research will give you all the information you need to make an informed choice.
