I love it!
And if I ever went to a vendor's homepage and found "for news, check our Facebook page" - well, that would be the very last time I would visit their page. Let alone buy anything from them. Leading a customer (who intends to spend his money) on a wild goose chase is - to my mind - extremely arrogant, extremely rude and not good for business. Try this in Germany and you can close your shop. Word travels fast. And German customers do not like arrogant BS.
I do have a FB and have gone to one vendors FB to make a purchase only because he didn't have the typical online store but when I'm on a vendors site and I see "like us on FB to receive......I don't care what it is- I close that tab and find someone else.
In the 3 months I've been vaping I've entered 2 contest and both required also posting on FB. For me, it felt like overkill so I simply stopped entering contest.
