StreetDeal's premium membership is SCAM! You have to pay S$9.9 every month for 10% off. But, you have to subscribe this membership for at least 6 months, if you early terminate, there will be a PENALTY fee S$54.6!
They said you already aggree with the T&C, but the T&C is very hard to find. In their advertise page of the premium membership, no word state the 6 months period and the early penalty fee. So don't greedy for small advantages.
For their deal, actually not good enough, even you have the additional 10% off, the price still not as good as the other deal site, last time I bought a gelish deal from them, I have to pay another S$20 for manicure! And the food deal also sucks, don't believe their pictures!
