@Bama Samurai said, flipping blades is unnecessary. Especially if you are only using it for about three shaves anyway. You don't need to wipe them or take them out of the razor before discarding them either. To clean them after shaving, rinse the head of the razor under running water and shake. That's all that's necessary. Unless you are using old-style carbon steel blades, and then you do have to rinse and dry them each day or they rust. But none of your sample blades are carbon steel and there's no need to play with them until later if you really feel you must or want to.
If you only have one of each blade, I would use each for three shaves each and try them in turn. Save the Feather for last. In the meantime, I would order a 100-pack of one of them to start with.
Since you live in Canada, two good places to get stuff online are Fendrihan.ca and Canadianbladeco.com. Both are in Canada so you avoid the whole Customs thing, and both also offer free shipping over a certain amount, or very reasonable shipping if you don't reach that level, and both have excellent products and good customer service. For razor blades, Fendrihan is the best of the two because it offers 100-packs. It also offers samplers of tucks of several brands if you want to experiment. Honestly, though, you are probably just as well off to pick one reputable brand and stock up a bit, at least to start. Later, if you want, you can experiment with different blades to find your "perfect" one if you want -- although by then you will probably have found as many of us have that any quality blade will work just about as well as any other.
Of the ones you have as sample blades, Fendrihan offers Astra SP blades in 100-packs for $18.00 Cdn -- roughly 20 cents a blade by the time you figure in tax and shipping. If it were me, I would order a 100-pack of them from Fendrihan and maybe throw in one of their sampler sets of other blades to play with later once that first 100 was gone.
You'll notice that the GSBs, Gillette Platinums and Feathers -- which Fendrihan also sells in 100-packs -- are all significantly more expensive than the Astra SPs. And certainly to start, I doubt you will really notice that much difference between them. So get the good but cheaper ones.
Or if you find you like the Rockwell blades, then get a 100-pack of Rockwells from Rockwell for about the same price as the Astra SPs and use them. Either way, you aren't going to get a good razor blade for much cheaper than that in Canada.
If you want to use Voskhods, PolSilvers, Rapira or the other Russian-made blades (other than Astra SP or SS), the cheapest place to get them is by buying in bulk direct from Russian re-sellers. Neal
@NCoxSTL can tell you how to do that. (I can't remember the website at the moment).
By the time you work your way through that first 100-pack, you will be an expert at using your razor (and lathering your soap if you are just learning that) and can better appreciate the frankly rather subtle differences between the top-rated blade brands.
Edit:. I forgot ItalianBarber.com -- another good internet store based in Ontario. And they have Voskhods on sale at the moment for $14 Cdn per 100...
