I use Front Page also, and it can be easy to get a lot more and
tags in there than you mean to. You might want to select all
the text in a page, make it all default, normal size -- then use header
tags to set off headings.
I'd look at reorganizing and adding to the information on your pages --
why not separate pages for adult, kid, holiday, etc.? It isn't clear
to me whether the numbered collections all have a combination of
several types of games, or whether some have a concentration of one
or two types of games. Someone who wants kids' games might not want to
pay to also get stag party games!
And some more description would be good for the games -- what does
someone get if they order collection #1? A booklet with instructions?
Blank forms to use in the games? Props of any sort?
How about a sample or two? You could showcase one of the games --
give the instructions illustrated with photos.
And caption the photos! Let us know which games those people are playing --
the captions could go into ALT text as well.
