Legally yes if you can get anyone to pay your prices is another story
You would need to be authorized to re-sell their products...
Youre not likely to find support from a boss in that endeavor. Your boss will see it as possibly and probably taking away from your production at work. Dont pursue it.
Your company may not like at all, that you are soliciting business within their business.
There is no law against it.
IF those you are selling to are prepared to pay for them.
Yes you can.
you can try but probably won't go over all that well
Don't know. CAN you? Maybe you should ask your boss.
Yes, it is called business - u buy in one place and sell in another
Only if you got permission from your boss.
Since we don't know your employere's policy about this, how would we know. Legally, you probably need a re-seller's license. Most employers discourage this type of activity (by discourage I mean one warning and then you get fired). Finally, why would anyone buy stuff from you at a mark-up when they can just as easily go to the same place and buy the stuff cheaper. And on a different note, I am not sure that your co-workers will be happy with you trying to make a profit for yourself in this way (for a charity, they might buy in, for a personal gain, probably not).
