There is an example application supplied with EPiServer Commerce which is a fully working implementation. You should probably start but picking through that and seeing how each element is achieved.
I'm new to Episerver commerce and I would like to have some tips on how's the best way to learn it. Is there any good tutorial like "Creating an Episerver site from scratch" in the net that you guys can recommend? I've started reading the SDK but i would like to find something more "hands on".
Thanks in advance,
