This is why I almost never buy Renderosity bundles... that and the fact that items purchased in bundles usually don't trigger the "already purchased" indicators in the store. I inevitably have at least one of the items and given that the bundle discounts are usually at less than the better sale discounts, it's just easier to wait. The sad thing is that one of the other major CG stores, CG Bytes, has a bundle system that automatically credits you for the value of your existing products, and I buy bundles there all the time.
