I used both thamel.com and mucha.com once each.
muncha.com delivered the goods exactly on the perfect time.fully satisfied with their service.

Thamel.com messed up all the surprises. They were supposed to deliverd a SAREE & a CAKE  to my Girlfriend on her birthday. to my surprise they called her the previous day to inform that the saree i choose is out of stock so that she need to go to the boutique to choose the saree.....The Cake  was supposed to deliverd in her office at 1.00pm but was delivered to her father at home at 7.30pm....Moreover the cake which they delivered should read

HAPPY BIRTHDAY..............

HAPPY BIRTHDAY FATHER
