I worked at a major pharmacy chain recently and heard alot of good things about Oscillococcinum, watch the ads in Walgreens and CVS because last year they had those for like $2 a box for like a month.
Also we picked up alot of our supplies from mask, med, and tissue for next to nothing by talking to some of the managers and finding out when they are expecting module or revision changes. About 6 months ago some of the Walgreens went to a low profile store and from what I heard at a corp meeting this would be going on all over, this resulting in some major clearance in stores. A little studding or blowing some time at CVS, Walgreens, or other chain store ( smaller ones can scoped out in a smaller amount of time ) can save you some $$
