I want to develop an eCommerce website (shopping cart, online payment) for retailing eyewear products. This would require certain features such as prescription Rx input and selection, optional add-ons, and functionality features such as virtual glasses try-on. End result should be similar to warbyparker.com.
Also to clarify the optional add-ons, I require a "purchase with purchase" feature, and multiple choice package.
Prefer 2 different methods for check out process:
1. Local (payment without shipping charge, Self-Collect option at selected local store)
2. Global (100% ecommerce, include shipping charge)
To clarify the "Purchase with Purchase": Buyer adds item A into cart, option to add item B at special rate for combo purchase. This may involve multiple combinations.
Also require some flexibility for offers (e.g. free shipping with minimum purchase) and provided in a simple step-by-step process.
