Hello,
There are quite a few merchants that say it's unbelievable Shopify doesn't do [insert functionality here]. The team at Shopify does their best to satisfy most requirements, while building a great platform for 3rd party developers to support even more requirements, such as yours.
Imagine a customer coming to your shop and saying "It's unbelievable you don't have this shirt in orange color!".
We'd like to followup with you, and maybe provide a cheaper solution (but not free) to satisfy your need. How can we contact you?
Thanks
