Gibb shop question
If I have a lower tier trap that has enough cards to upgrade to tier 7 and I receive another card, will I get gibbs? Will I have to upgrade the trap fully to receive the excess gibbs? I currently have 9 up-gradable traps that I am sitting on because they are far less useful to me and I don't have the 16,900 skulls to upgrade them. I expect to be in the situation described above before the gibb shop gets released.
