80 tooth blades that size are great for crosscutting or small chopsaws as it will minimise tear-out and chipping without the hassle of making a 0 clearance insert or backing the workpiece. If you try ripping with one unless the wood is very dry the blade will clog and generate enough heat to dull it almost instantly. Would be ok for MFC.
@ILB erbauer may be a Screwfix brand. It's certainly only sold in the UK by Screwfix (no idea if it even exists outside of the UK). So it's likely that they are taking a leaf out of evolution's book and dropping the price of a saw because only they are able to supply hassle free blade changes (in much the same way that razor blades often cost 2x as much as the actual razor). With regard to the track; you bought a precision tool if you don't think it's precise take it back and get another one or something a bit better. Edit I see you've already decided to take it back.
I can see that being a good way of recouping costs, but even in the Screwfix Q&A they admit that they don't stock a replacement blade. Seems mad to me. Still, at least I haven't used the thing before finding out.
Another reason to take it back is that you need to join 2 of the tracks to cut across a sheet of ply and the tracks supplied won't cut the length of a sheet. This is severely limiting to say the least.
