To be able to work with living social company ,they will be selling my enerviv product and the client receives a voucher number and they claim their purchase in enerviv website ,the price of the product on the shopping must adjusted to $0 and only the customer pay shipping, we collect their information to ship product and after I have to go to living social and redeemed the vouchers used buy buyers . Note : • The voucher number must be use only once therefor when the customer enters the number must be blocked from being use again. • My website must keep track of the vouchers numbers to be able to obtained these and report to living social merchant website. The report must be generated by my website with a format compatible with excel this format is specify by living social. • I want to use my existing web design for now to speed the completion. The website is [login to view URL] Additional information that was provided by living social company: I understand there's a bit of confusion regarding how customers will be redeeming there vouchers. To clarify, here are the redemption instructions we have set up: 1) To redeem, visit [login to view URL] 2) Be sure to enter your deal and voucher code prior to checkout 3) Enjoy! First, the customer will click on the above link, or they can copy/paste into their web browser. Once there, customers click "checkout" and fill in their billing/shipping information. Once they have confirmed their information, they will enter their voucher code into the "coupon code" field on this page: Once the code is entered, they will click "place order". Since shipping and handling is not included, customers will only need to pay the additional $3, as the voucher should cancel out the value of the supplement. On your end, you will need to upload any voucher codes that have been assigned, which can be found in your Merchant Center account under the "Customers" tab. Unfortunately, we cannot coach you on how to upload the codes to your system, as each system is a bit different. I would recommend talking to your web developer for additional information in that regard. If you need specialized codes, please let me know and we can provide you with some. Otherwise, you can easily download them from the Merchant Center as they come in. Once these process is done .I will let you know about the second stage which is about a system to manage a multilevel sales such as Herbalife similar system . I want this system to be part of the website .
