Zencart Shipping Calculator

We are working on Zencart shopping cart solution for our ecommerce website. Currently our web order volume is very low and we are hoping that it would pickup down the road. We currently have 3 methods for calculating the Product pricing and shipping Charges. Currently Zencart allows any one method for shipping and handling calculation mechanism. But we want all the three methods to be used. Here is a brief description of different shipping and handling calculations: 1st Method (for Books): If customer purchases 1 book shipping Charge should be 9.5 and each extra book 1.00$. Ex: if they order 5 books shipping charges like 9.5 + 4 = 13.5 NOTE: Here we are using volume based shipping. 2nd Method (for Forms): Forms shipping and pricing method is different like discount based Cases Product Price Shipping Charges ---------------------------------------------------------------------------- 1-4 $32.48/case $6.99/case 5-9 $29.98/case $5.99/case 10-39 $27.48/case $4.99/case 40-100 $22.48/case $3.99/case Example: 1-4 Cases Product Price is $32.48/Case and the Shipping charges are $6.99/Case 32.48 x 4 Cases = $129.92 (Product Price for 4 Cases) 6.99 x 4 Cases = $27.96 for 4 cases (Shipping Charges) 129.92 + 27.96 = $157.88 for 4 cases (Product Price + Shipping Charges) NOTE: Here we are using discount method on prices and shipping charges. 3rd Method (for Envelops): For envelope we have drop down menu like Plain and Imprint Ex: if customer orders plain Envelops 22.5 + 3.99 Shipping charges If customer orders Imprint Envelops 22.5 + 40.00 (Imprint price) + 3.99 Shipping charges Note: here we are using flat method for shipping Here is the test website: [[login to view URL]][1] ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
