A question about credit/charge cards....

Ok, so I have decided that sometime in the near future, I will probably start a small (4 - 6 plant) growroom in a closet. I have the finances to buy all of the equipment needed. (lights, rockwool, pots, buckets, ph kits, etc.) I have one question however. I have heard many places to never buy these items with a credit or charge card, as the DEA buys the information from the suppliers. Now, I know that this is true, it is in no way inconceivable.

My question to this community is:
Is this just being over paranoid?
Do my purchases really need to be made with cash?
Remember, it is a very small operation.
Has anyone here ever done anything like I am planning with a card?
Anyone you know ever done anything like this with a card?
If so, what was the outcome?

The reason I ask is because it would be about 1000000000 times easier to just get the stuff off of the net.

Thanks in advance!

Buy it with cash just to be on the safe side. I wouldn't risk it, no matter the size of the operation.

thanks for the advice!
