For the most part, I've been sourcing my components from either Mouser and or Digikey, but lately I've started placing one-off bulk orders with AliExpress. You can typically find what appear to be great prices on larger quantities of discreet component, but then there's always that large shipping fee (at least to the US) and the significant wait time for deliveries (which typically take 4-12 weeks in my experience). So, I decided to take a look at some of the components I need for a particular BOM and compare the actual costs, side-by-side: In each case, I tried to source the cheapest components from reputable suppliers with the most positive reviews and feedback. You'll notice that the volume and quantities aren't exactly the same for all items, since Mouser required some minimum qty. for certain items. But in the end, the cost delta worked out to only be around 9%, so I decided to stick with Mouser for most of this order and benefit from the trusted quality and faster shipping time. Apologies if this is stating the obvious, but the exercise was helpful for me, so I thought it was worth sharing. Cheers, -Darrell
