IDT
Oligo synthesis
I've tried a couple oligo synthesis providers, but have had the best experience with IDT. Even late afternoon orders are usually delivered the next day.

Almost always delivered next day
I've had positive experiences anytime I've had to deal with customer service and they have always delivered my oligos quickly.

Out of several oligo synthesis companies I've tried IDT is the best. Sometimes the pricing is a little higher for large orders, but it's worth it.
