Count yourself lucky it didn't get bigger... Trying to compress an 
already compressed file almost always gives an output file that's larger 
than the original input.

In this case, I'm thinking that zipping/stuffing isn't about trying to 
compact the files further, it's about the archiving capability - Instead 
of X number of files, each representing a page, it's one file containing 
some number of pages.

Zip 'em up grouped by issue (or perhaps 10 pages of an issue), then even 
though the archive ends up larger than the equivalent single files, it's 
a "start the download and go have coffee" thing, rather than "Start the 
download, wait for it to finish, start the next download, wait for it to 
finish, start the next download... lather rinse repeat".
