Just for your information - I recently placed an order for a batch of L91 & L92 “Nice” brand primaries from FastTech. (They’re less than 1/3 the price of Energizer Ultimate brand here, and from my experience there’s little, if any, difference.)
They shipped by surface on Oct. 10 and arrived today (Dec. 10). Two months to the day, from China to Canada. I’m well satisfied with that, when you consider that other goods shipped by air often take six weeks.
