Create a rule for collections that behaves between "distinct" and "same items"
Not sure if this is currently possible, however if it isn't here we go.
There really needs to be a way to make it so that the deals can be claimable whether the customer has several of the same item or 1 of several different items. From what I've seen in the rules so far, you can only choose between having the deal be claimable between those two options which might annoy some people who just wanted to buy 3 of the same items but couldn't get the deal. And if there are tons of deals already on the store, having to create another set of every deal just for being able to claim it as same item or distinct items only would only make it more cluttered among all the deals there are already.
