It's not "more expensive" but after the rebate period has passed, one doesn't get the 25% off for joining the GB.PollandAkuma wrote: ↑How much more expensive are the sets after the GB/as leftovers?
Leftover kits are listed in their original price, and the "Grab bag kits" despite usually incomplete are the most economical usually at just a fraction of the original price.
7bit has extended the 25% off rebate deadline of Round 7 from some time in November 2016 to December 31st 2016, and according to previous Rounds, it is also possible that the rebate period of Round 7 be extended a bit more. I think as long as the invoice 7bot sends you has the rebate information, you can still get it 25% cheaper.
Just check them out, Grab Bag kits of Round 5 and Round 6 have some real goodies indeed.
