I just read an article it mentions this:
What do cash-on-delivery offers have to do with call centers? Do they have to make a telephone call to somebody? I've never seen this service before, but I think they only need to give the money to the people who deliver their products, then the couriers will forward the money to the sellers somehow.It is obvious that during the pandemic Nutra was going through hard times, COD offers were especially affected due to the shutdown of call centers.
