Amazon stock fractional shares now that they are splitting?

I have a very modest income – between $45k-$50k/year, but have no debt and am 40, so I still have time to invest. I am thinking of pushing about $50 – $100/wk into Amazon fractional shares until they split. This is a company that I like quite a bit, and do own some technically through index, mutual funds, and etfs in my ROTH and 401k, however I don't own any outright. Is anyone else planning on doing the fractional shares or stock slices until they split? Obviously I can't afford even one share now all at once, but I figure this might be a good way to get into the company.
