Here’s a price comparison I did back in 2019 (presumably still correct?). But in short, per nt price was cheapest through ThermoFisher.

Thus, we’ve been almost exclusively buying oligos from them, with $7,220 spent (as of June 2022) since our first orders starting December 2019.

But, well, don’t order degenerate nucleotides oligos from them as they’ll likely be T biased.
