These are all very different questions. First, Groupon offers limited time deals, so pointing you to several historically good Groupon discounts won't be of much value since they're expired. That said, I've personally noticed that Groupon tends to offer some of its deepest discounts on things like yoga and gym memberships.
If the product or service doesn't cost the vendor much money (eg. The gym is already open for business anyway), I've found that they're more likely to offer extreme deals. I think that Groupon is the best coupon website, at least right now.
They may not be the hottest site forever, but for now they're getting lots of traffic and publicity. Creating your own coupon website may not be incredibly expensive, but I imagine that competing directly with Groupon would prove to be difficult.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
