I've been beating my head against many walls with this. The last straw was a nice PDO error after entering 15 variations on a product and losing them all. My use case is, I think, extremely common. I've read the documentation, all the tutorials I've found, and watched RFEY's videos. I need someone to hold my hand through this.

Right now I'm trying to enter a bunch of shirts. For simplicity, I have two shirts: a hoodie and t-shirt. Each comes in four colors: Green, Gray, Blue, Black. Each comes in five sizes as well: Small, Medium, Large, X-Large, XX-Large. (see, pretty common). I have to include other fields as well, of course: SKU, price, shipping dimensions, shipping weight, and some categorization (vocabs) stuff.

I've created a Product Variation Type called "Tops" (tangent: why did the term 'variation' end up applied both to a high-level categorization as well as a singular item (SKU) called a 'variation'. That really confuses a lot of people at first, I think.)

I hope I've provided enough info and really hope someone can help me figure this out. Ideally each year we'd be able to update a single spreadsheet and use Feeds to import the entire list of products at once to add new and update pricing. My understanding is I would probably have to do an import for each Product Variation Type though, is that correct? Either way, understanding how to use Feeds and Feeds Tamper to get my shirts in will point me in the right direction.
