Amazon cuts up to 52% off a selection of Victorinox Swiss Army knives, with prices starting at $11.97. Even better, get an extra $10 off orders of $50 or more. (Discount is taken at final checkout; only Victorinox knives sold and shipped by Amazon are eligible for the extra $10 off.) Most items qualify for free shipping. (Some items may require Prime membership to bag free shipping. Non-members can spend $35 or more to qualify for free shipping; otherwise, shipping starts at $5.58.) That's tied with our September mention as the best extra discount we've seen on Victorinox knives at Amazon this year, although our September mention featured a higher base sale.
