Mecari gave me a coupon for an item I did not receive. I used the coupon amount for two more items, a watch and an alarm clock. Seller accepted my bid on the watch. The seller did not receive his money because mecari did not pay him for the watch they credited me for the watch. The seller then turned around and refused the sale because he can refuse a sale if has occurred in less than 24 hours. In the mean time Mecari counted the coupon against the failed watch purchase. Before this happened with the refusal of the watch sale, I purchased an alarm clock. Rather than giving me back the credit that Mecari offered me to begin with, they counted the failed watch purchase against the credit they gave me towards the purchase of the alarm clock. The alarm clock was totally defective. Don't use this site.
