The job fee seems to include shipping, which makes it more reasonable. But Aisler's "estimated dispatch" for the budget service is Jan 26. That's 10 business days + shipping, making it not very competitive with JLCPCB's 10-15 business days including the slowest/cheapest shipping.
Express service adds ~20 EUR, roughly the same cost as picking DHL express delivery on JLCPCB.
For higher-end board that seems likely. For cheap hobby-grade boards just the job fee[1] is more than 10 boards delivered is from JLCPCB.
That said, thanks for reminding me. Will definitely compare next time I need boards.
