I dont understand why so many people are upset. Sure, it wasnt nice to tell Nicecore about the coupons. But on a free market the sellers imo should be free to set their own prices so I dont really like Nitecores behaviour either. In Sweden the resellers are free to set whatever price they want (atleast in theory).
I also think we should not expect a deal to last forever. A deal that lasts for a long time is no deal but a regular low price, right? This time many of us had the opportunity to buy the lights from either group buy or from coupons from different members on this site. There was also email-coupons directly from atleast one of the big resellers.
But I´m just a noob, so I am probably very wrong. I am sure you will let me know
