If you are interested in reading about the process of conducting the op amp comparisons that I wrote about recently, I have posted a brief article describing the test circuit and what I plan as the next step.

[2733] International Mail Is Back

Date: April 1st, 2021 | Comments : [1] | Categories: DIY.

International First Class Mail has been reinstated by the USPS. I can ship international orders again at a rate close to the previous charge. is mostly dead. I can still send a Priority Envelope for $40 to $41 depending on the destination, but First Class mail of merchandise is no longer accepted for international shipping. I cannot even make a customs form for it using the USPS web site.

Sales to US addresses remains much the same with only a small postage increase. International ordering is open.
