I'd put off shipping for as long as possible when ordering parts off Digikey.ca. I'd add a part one week...add a part another week.. etc. I was stalling on shipping for months. Order was over $140. Then the pita started to build up. Items were starting to be no longer available and/or long lead times. There was an intolerable amount of missing stock at Digi that I have to transfer my order to Mouser which has stock.
Lessons learned. Ship asap before it disappears on Digikey. Good thing I'm not doing a small production run. I'd be part starved by Digikey. Mouser wins this time. Trust nothing. :P
