has the said razor blade refills for $24.18 with $6 off coupon. Can be combined with with P&G $10 off $50
A bit of self-criticism: although this beats a previous popular deal
by more than $3, for Costco members, I fail to see a deal here, since Costco price [costco.com]
is only slightly more per cartridge (after $5 off) for supposedly better "power" cartridges. Feel free to correct my math if needed.
