How often do package deals come along?

I've bought the last couple, with the Dark Naga and the Arcane, but I need to budget for buying gold, too. Is there a pattern to when these bundles go on sale, or is it more of a random thing? :confused:

It is random. Maybe once a week or so.

Usually Fridays, but (big disclaimer here just in case) this isn't guaranteed to happen each week and is subject to change.
