What is the ruling of the following transactions?
A (the customer) places an order of 10 000 bricks from B (the hardware store). B (the hardware store) does not have the bricks. Hence, B (the hardware store) orders it from C (the brick company). B (the hardware store) doesn’t take possession of it and instructs C (the brick company) to drop it off at A (the customer).
1. A (the customer) orders 10 000 bricks and pays for it in cash to B (the hardware store). B (the hardware store) then orders it from C (the brick company) and pays for it in cash. Then B (the hardware store) tells C to drop it off at A (the customer).
2. A (the customer) orders 10 000 bricks from B (the hardware store) on account. B (the hardware store) then orders it from C (the brick company) on account and tells C to drop it off at A (the customer).
3. A (the customer) orders 10 000 bricks from B (the hardware store) and pays for it in cash. B (the hardware store) then orders it from C (the brick company) on account and tells C to drop it off at A (the customer).
4. Same as the above mentioned scenarios, but instead of C (the brick company) dropping it off at A (the customer). B instructs D (his driver) to drop it off at A (the customer).
5. Same as the above scenarios, but instead of C (the brick company) dropping it off at A (the customer). B instructs E (the courier company) to drop it off at A (the customer).
6. Same as the above scenarios, but C (the brick company) instructs E ( the courier company) to drop it off at A (the customer).
