Advertising an item that one does not have possession off

Q:

1. Say I place advertisements for commodities that I do not have possession of. The advert will not mention that I do not currently possess such items. Anyone seeing the advert the will be given the impression that I do possess such items, but no lie/deception will take place. Then when customers contact regarding these products I will take down their orders, but not take payment. Only once I purchase and physically possess these items from my supplier, I will then contact the customers regarding payment. Is this manner of advertising commodities that I do not have possession of permissible?

2. After paying the supplier for the product, the supplier sends it to me via a courier company. Whilst this product is still travelling to me across the country in the possession of the courier company, but nevertheless after I have paid for the product, can I sell such a product to a customer?

Waiting for a little while after istinja

Q: I have a weak bladder due to which I cannot hold urine. After doing istinjaa I know if I will wash my private part and during washing if I try to hold my bladder, urine will come out because it cannot hold my urine which come's out due to pressure put by me trying to hold my bladder. Am I still considered mazoor? Can I still make wudhu when I know that urine drops which come out is because I have tried to hold my bladder during washing my private part? I mean before washing my private part I know if I hold my bladder, urine will come out due to it's weakness and I still make wudhu. Will my wudhu be valid? I know your ruling regarding mazoor and sorry for asking a confusing question.

Water collecting in the tub while bathing

Q: We shower in a tub. When we take a shower, water collects at one end of the tub though the tub has a drain but the water collects at one place and we use our feet to push that water towards the drain. My family members sometimes don't push the water and use the towel to wipe their feet and then place the towel with mine. Will my towel become impure? Sometimes the water seems soapy.
