Can anyone recommend a Slumberland dealer that will give a good price on a mattress?

After testing out mattresses at Robinsons and various shops I think i've found the perfect one - Slumberland Crown Jewel. I would classify it as "cushion firm", it doesnt have the bounce of latex neither is it immobilising like memory foam, somewhere in-between.

Unfortunately the asking price at Robinsons, and a slumberland shop on Jln Maarof Bangsar was rather steep RM5200 and RM4800 respectively for queen size. Waaay beyond my budget - and doesnt even include the divan. Are there better places to look?

Anyone tried Sanctuary (bio ceramic)? The pillow top is using similar materials as the Crown Jewel but somehow i feel that the springs are much harder.
