Occasionally omitting the sunnah ghair muakkadah before Asr and Esha Salaah

Q: We know it is sunnah to read 4 rakaat salaah before the Asr and Esha Salaah. Will it also be sunnah to purposely leave out these sunnah salaah SOMETIMES, as it is Sunnah Ghair Muakkada. 

Ezample, a person reads the 4 sunnah of Asr on Monday and purposely leaves it out on Tuesday and reads it again on Wednesday. Will this be regarded as a sunnah?

Selling various products via Whatsapp or a website

Q: 

1. I sell products from my business website. My supplier has 200 products. I stock 100 items but list all 200 items on the website stating 'available on order'. The customer purchases and pays for the item and I then order and ship it to the customer. Is this permissible? 

2. I post items on my WhatsApp for sale... Customers know I don't have the product. The supplier has numerous agents like myself who advertise and purchase according to order. Customers place orders and once I receive the item, they pick up and pay. Is this permissible or how can this be structured in a permissible manner?

Issuing a talaaq while being forced

Q: My elder brother, recently and was forced to get divorced from his in laws. He was under so much pressure from them, and he was alone at his rented house, and they all forced him to say yes for the divorce. 

But now he is saying that he has not said from his true heart to his wife that I need the divorce from her. So please advise if the divorce is done on his wife or not, because my brother is saying that he has not given her divorce by his heart, but was under pressure from his in laws.
