This is what I bought:
-> $4.22 Q-tips Cotton Swabs 500 ct -> $16.32 iPhone 5/5s, iPhone SE, iPod Touch 5th/6th Gen Adidas Nylon Armband Case - Sports armband for adidas miCoach training system -> $6.95 iBungee Stretch Laces (26-Inch, Black Laces with Black Race Lock) -> $4.79 4 Philips AA Zinc Chloride Double A Batteries R6 1.5V Super Heavy Duty Battery -> $8.10 Monoprice Apple MFi Certified Lightning to USB Charge & Sync Cable, 3ft White -> $89.96 ASICS Men's GEL-Kayano 23 Running Shoes T646N
The order for the phone arm-band was cancelled and everything else shipped _separately_ - I Literally got 5 different packages in the mail - over a week with different items.
Had I gone with Amazon, I would have received - one, maybe two packages with everything. Infact, Jet probably lost money on most of the items they shipped to me.
Us techies sometimes tend to forget the real world (in this case customer experience) while playing with cool technology.
To me, an old fashioned optimizer running on a 15 year old AMD Opteron that delivers the appropriate real-world result is worth more than that F# and CUDA thing that seems to have over-optimized the problem to create a bad customer experience (getting 5 packages in a haphazard way).
