They are so dishonest, it's an appalling tactic that is surely to pressurise people into buying.
This is an even worse schlocky outfit than I thought, disgraceful.
I work in sales and, despite people's perceptions, we do not have sales only 3 times a year, but have special offers all year round. I always have customers asking me how long a laptop is at a certain price, or a range cooker. The truth is, and I tell them this, we do not know. No way have I ever contemplated telling them to buy it now, as it will never be at that price again. If I did and, subsequently, the price was reduced, or repeated, the customer could come into store, and complain. With presenting on a shopping channel, there are no consequences, they never have to be in contact with, let alone see, the consumer. They can do and say whatever they wish.
I pride myself on my integrity, something the presenters - they are not sales people, with product knowledge, etc. - are lacking.
