The 500 should last a tad over 4 years and yes I shave every day. I maybe skip a couple of days in the year but in the main it is every day and usually it is three shaves per blade regardless of cost. Sometimes I have pushed it a few extra shaves just for fun but it really is not worth it.
I currently have about a 60 year supply (roughly 7500 blades), some of them I may use for two shaves but most for three. Like HM I am going through the turmoil of deciding not so much which ones I hate, more the ones I like the least and intending on trimming back to my favourite favourites. I got my first sampler a few years ago and intended on working my way through it and then bulk buying the best ones, what happened was that by the time I got through the pack most of the ones I liked were out of production, eg. Gillette Silver Blues (Czech ones) Nacet (Again Czech made), Swedes, Polsilvers, Wilkinson Sword (UK ones) all gone. So now I buy a few packs and use that blade through a few different razors, if it passes that test I buy either 500 or a 1000.
Even some of the the soaps I liked have changed their formulation and/or scent so I do not take any chances these days. Buying in bulk at the right time and from the right market has allowed me to get slightly more for my money, so if I change my mind I can sell at a normal price and as long as I cover my costs and the postage I am happy. The way the interest rates have been over the last few years blades are a more stable currency :lol:
For instance when the currencies dip and you are one for one with euro and dollar I scoop some blades with a better exchange rate or get more blades for the same amount. Right now the share prices are shite butfor a while so was the pound so I sold some of US company share options and because the shares are in dollars with the one for one exchange rate I end up with the same amount (or slightly more) than I would if I waited till the market way more buoyant, in that case the pound goes up and you need more dollars to the pound.
Weird but true, I just keep a tally of what the cost of the item was at the time of purchase and this is the target to sell at, doesn't always work mind you, you win some you loose some.
To say that you've hit the ground running is a gross understatement! That's an absolutely brilliant start, and you're in for a lot of fun and enjoyment. :lol:
