I found out through perusing some review sites that apparently the Russians make the best DE razor blades (who knew?). I went looking for Voskhod blades as these looked to be the best for my skin and found them at Amazon for a decent price, only to find they were subject to shipping unless I purchased $49 using a Prime membership. I then stumbled across vshod.com where I found them for $2.00 for 10 blades and included postage. It's a Brisbane-based seller who runs a PayPal-only store, so the site design is…interesting. I figured $2 wasn't much even if the seller didn't come through, but 3 days later they turned up as advertised. He actually has quite a range of different brands of blades so you could easily build yourself a sample pack to try them out, which is what I plan to do later.
He also stocks a wide range of DE razors, too, starting from only $12.95 for a plastic handle and many that are $20-$40 which look half-decent. Again, postage is included.
On the surface it looks more expensive than Amazon until you start factoring in the shipping cost, plus it's a genuine Aussie seller.
Do you have a link to the review sites vouching for Voskhod blades? Not doubting you, it has been a while since I did any research, but I remember Reddit recommending brands like Feather, Astra and Derby. I haven't heard of Voskhod.
