Fujitsu-branded premium grade batteries. Used them before this deal and they seem to do the trick (nothing out of whack from my observation of use).$0.50 each package but $0.40 with PSP. Made my purchase at this price and received them already. Expiry was 2026, so plenty of shelf life left. Good for those who bought the NERF laser tag unitsAt this pricing, not sure why the website does not list them as discounted because I've seen these ones at much higher pricing (good for RFD I suppose). Compared to buying any other type of alkaline battery (even the dodgy Dollarama ones), this seems to be a stellar deal at $10.00 for 40 AAs or 20 AAAs (or @$8.00 with PSP).AA 4-packAAA 2-pack
