I am a long-time Groupon user for everything from tools and pillows to vacations and massages.
They have been on a steady downhill run for YEARS now and it has finally simply fallen to scam purchases.
They offer "coupons" like a $40 flower delivery for $20 (shipping included). When you arrive to blooms.com they add another $27 to your purchase and you are only allowed to select from 6 different (cheap) bundles anyway. Saving less than $5 for a huge voucher headache and crappy selection.
Even their vacations SUCK now and include 36-hour layovers at random airports. WHAT KIND of vacation package includes a 36-hour layover in Memphis with no hotel accommodations?
They allow sellers to brazenly SCAM customers and even after h8undreds of 1-star complaints continue to sell the scam groupons.
The customer service is about as incompetent as copy/paste customer service as you can get. Asking for screenshots of the issue in response to you emailing screenshots (not even reading the emails, just the SAME copy/paste response over and over until you go away).
Groupon used to be a decent place to get great deals on services and goods. Now it is just a place to advertise "fake sales" (advertising a $50 item as a $100 item with a $50 discount when it is $30 on Amazon), SCAM services (companies that will not allow you to redeem the coupon), horrible vacation packages (massive layovers), and to top it all off the most incompetent customer service that I have ever dealt with.
