Costalize aims to revolutionize the way we shop. Costalize enables consumer to first experience the product and then pay what they think is the right price. In other words, price setting power remains with the consumer rather than the seller. Costalize allows buyer and seller to communicate with each other in order to share opinions about the product, present arguments and set a price for the product. This will benefit consumers as well as the businesses selling their products. Consumer can save on their favourite items while businesses can market their products in a very effective manner. Consumers can also communicate with each other and share ideas and experiences which will further enhance their shopping. In last few years, shopping is becoming very consumer oriented empowering the consumer more and more. Costalize will take consumer empowerment to new levels as it will give the power of price setting to consumer. There are other features also on Costalize to benefit customers.
