T-Shirt Upsells for a Family Registration

Halton Down Syndrome Association

I'm looking for a work-around for the following scenario....


We have a Walk and we're offering optional t-shirts for $5/person. We only have 1 registration type - it's called a "Household Registration" type because we have families and kids and find that offering one registration type for a certain amount worked really well for us last year, made the registration process smoother, and avoided duplicate e-mails. As an Upsell, we're offering t-shirts in toddler, youth & adult sizes (we had to break out the upsells into two: 1 for Toddler/Youth and 1 for Adult because we have 13 total sizes and you can only have 10 options per Upsell). However, as a "Household Registration", most of our households have multiple kids and multiple adults. Upsells are only checkboxes or drop-down options that we're already using for the sizes. So we have no quantity option. So the person registering can't say they want multiple sizes of x youth shirt or multiple adult shirts.


The only solution I've really come up with is having MULTIPLE Upsells - i.e. 2-3 Adult t-shirt Upsells and 4-6 Toddler/Youth t-shirt Upsells (I believe our largest family has 4 or 5 kids). This makes for an incredibly long and text-heavy registration page, I fear it will be incredibly confusing, and no one will buy t-shirts.


Any ideas??
