Hi,

so here is my modeste vision:

5 products in one copy is ambigus, it will make ambiguity to the reader, he (reader) will order for witch one of them, and the copy will be longer.

here an idea, why not to make each of them on his own domain name (40-50$) of investement, and to target 5 time, and to have 5 time traffic.

it induce a huge work, but it is better.(in my modeste vision).

now, if the package are complement (i mean 1 will need the package 2)etc..., then you have to redirect your reader after the order (in the package not in the site) to the second etc..

this is my modest vision (I havn't try it before), hope just that help.
