You should call sales... they will take into consideration your previous purchases... they have with everyone on here and have been very fair about giving previous customers better pricing options.
Also, it is a little different in what you spent money on... you purchased the licenses, so you own them forever. Someone may be able to get access to all extensions for 199, but that is a subscription and has to be renewed every year. It is good for someone like me who wants the most up to date release plus any new products when they come out, but that option may not be as efficient for everyone else.
