Ecommerce duplicate titles question!

Hey guys! I`m dealing with an E-comm store where they sell personalized items - all items look the same and have the same product titles - the main difference is that they are made for different age groups so there are different categories - for example: gifts for 30th birthday, 40, 50, etc...

The problem is with duplicate page titles - any idea how to fix this?

Thanks!

probably not the answer you want to hear but a good way of "fixing" it is by re-structuring the site to have all those products in one category (named "gifts" for example) and have the age groups used as filters instead of sub-categories. There might be other ways, but I can't think of them at the moment
