We are looking at moving our site to magento now. I have found magento will offer every options we need for an apparel site. However, I cannot find this extention. Is it available?
Need the ability for someone to place an an order by adding all the sizes and colors to the cart at one time. Here are couple options other apparel sellers offer and what we are looking for.
Screen shot http://screencast.com/t/8SpcfLlL2 allow you to choose the color you would and add all sizes to the cart at one time. It also provides the stock qty for each size. When you choose a different color the main image chages to that color.
This one http://screencast.com/t/tGOVmOH5KN does the same thing with a little differnt view.
This one http://screencast.com/t/LsF1NdZPWj2a shows the each color with the price and qty for each color and size.
Of the ones we like the best is the first screen shot.
I found one extension that is similar to what you are needing, but I don't know if it fits your requirements 100%. See if this helps.
