Fun site, the magic is this one line:
" Need a custom logo? Let’s chat! yo@metafizzy.co "
The chance of you needing one of the pre-existing logos is small, the chance of needing a logo period is higher, and seeing the portfolio of logos gives you a starting point to imagine things.
The only negative is that it might anchor you emotionally to a lower than average price if the current logo price is small enough.
The web site concept though seems to be exactly like a clothing store putting last years clothes out on the side walk for "cheap" and just getting people walking by to think about it and come in and browse. Which solves Internet company problem #1, "Nobody knows I exist."
