If I buy license for two device right now, can I still get discount prices in the future?

I need cover for two devices right now. In three-six months time possibly up to three more devices. Can I still get the multi-device/multi-discount offer for the additional devices as and when you need them or do you have to buy a license for all five devices at one time?

Eset licensing procedures vary by country. Best you contact the source from where you purchased your existing multi-seat license about this issue.
