The Inked Nib has Noodler's for $9. Does anyone know how much Pam's sells it ?

Wow! You found some deals, Betty!

For Sheaffer Skrip (Slovenian), in the 50-ml bottles, at Vroman's here in Pasadena,

the total including 8.25% sales tax is $5.95 USD per bottle, or $0.119 per ml.

It's the best ink deal in the store, and an excellent brick&mortar, non-bulk-packaging deal for washable ink.

(Edit: clarified the referent of the "wow")

That's Swisher's price too.

Pam at www.artbrown.com is selling Noodler's for more than that unless you buy a case of bottles.

Pam at www.apenloversparadise.com is selling Noodler's "standard" line, including the standard bulletproof black, for $9.95.
