If you can buy online, the dextrose and malto are very cheap. Probably the most cost effective sups you can buy. Especially since you will probably only use them post workout. You can also save a ton of money buying your protein online.

Are there any specific sites you can recommend, bareing in mind i'm in the UK so shipping may be an issue?
