Permissible and impermissible items of trade

Q: I bought a TV with option of no cost emi of 3 months. After emi completion, Later I found out that it is not permissible and it involves interest as bank gives loan and charges interest and then I checked my statement and found out.

I usually buy items paying all amount but this happened first time that I had to take this option of no cost emi. From the day, I came to know I am feeling bad. Should I sell of my TV or keep it? If I sell I won't even get 50% of amount which I took. So I am in a dilema. What should I do in this case.

Q: I work as a sales processed in a bed factory. My work is halasl but one aspect is concerning me:

I recieve requests from customers to make bed labels which the company has already designed & they contain silhouettes of 2 animals - the silhouettes vary in size, most contain a head 1 mm in height but some larger.

Before I send the request to the printing company, the customer previews the labels where the silhouettes can be clearly seen. Would I be sinning by sending the online versions & also sending the request to the printing company to print?

Would it be permissible to buy this car (Taurus) from this company or any other car from this company (Ford) ?
