Yes, you should ask for the sale. But "So, would you like the blue or pink one?" might come across as a bit pushy. "would you like to discuss pricing?" is more of a soft close.
There's a subtle difference there - the first is asking "past the close" but also is asking a pertinent question about it - people who want it will have a color they want, or need to pick one.
Nobody wants to discuss pricing. It's orthogonal to getting the desired end. You have to discuss pricing, but it is not on the list of things people want to do (if you give it to them free, they won't protest). The second is way too easy to say no to.
I think the difference is willingness to be pushy if that pushiness results in more total sales. Which I take as a symtom of general lower consideration for others, objectifying them as a system you just need to press the right buttons on to get what you want.
[edit] Another way of looking at it is what a culture considers acceptable freely-given consent. If someone wouldn’t have said yes if you hadn’t pulled out every trick in the book, is that an OK way to get a “yes”? In US business culture, it is.
I think it might seem pushy to people that are highly skeptical of the product, but in most cases, a sale is implied. When you go to Starbucks, they ask what they can make for you. They don't say "Let me know if you want to talk price."
Car sales is another obvious example. They don't talk price until you're committed (at least in principal) to purchasing the car.
Early on in the call, tell them your price to see if they object. If they do, then get off the call. If there's objections, raise them early and either overcome them or figure out that they can't be overcome.
