&gt; One screenshot hurts their entire argument, because I cannot take the rest of what they say at face value. Notice that the $18.49 package gives five razors while the $14.99 package gives four razors. The $3.50~ markup is due to an additional razor being provided.<p>No, you&#x27;ve  misread the packaging.  Both packages contain 4 razor cartridges.  The number 5 you highlighted on the women&#x27;s product advertises 5 blades per cartridge (same as the men&#x27;s product) but the package contains only 4 cartridges as you&#x27;ll see if you look a little further to the right.  You can see a higher resolution photo of the product and some more details here: <a href="https:&#x2F;&#x2F;shop.riteaid.com&#x2F;schick-hydro-silk-razor-cartridges-4-cartridges-0368651" rel="nofollow">https:&#x2F;&#x2F;shop.riteaid.com&#x2F;schick-hydro-silk-razor-cartridges-...</a>
