The description states :
Get all recipes for your tier of crafting in a single purchase! You'll be able to unlock recipes that can be found on vendors and in random treasure drops. *Note: Does not include any one-shot or reputation recipes.
Does anyone know how the Spring festival Tailor Recipes were originally acquired and if they are included?

It's not a one-shot recipe, nor was it reputation gated. It's simply no longer available to acquire, nor has it ever been available to acquire on the F2P servers.

I'd like to be able to make the cosmetic quiver for myself and my kin, and wouldn't mind spending a modest investment of TP for this opportunity.
