How should a recommendation handle an option above the customer's budget?
When a customer's request comes with a budget, the budget is part of the job. Check current prices and required charges, say so when nothing fits, and show a pricier option only as its own labeled choice.
The anticipatory panel used detailed shopping requests to illustrate changing customer expectations, and a request with a budget is a good reminder that relevance covers the constraint as well as the product category.
The headline price leaves things out
Before you call something a fit, check the current price and any charges the customer has to pay, since a headline price can leave required costs out. If nothing suitable fits, say what you could establish and what you couldn't find. Don't swap in what the system predicts the person might spend, because that replaces their budget with a guess.
The pricier one comes second
A more expensive alternative can work when it's appropriate, as a separate choice with the difference labeled. Put it after the answer to the original request, and word it so the limit the customer set still reads as a sensible one.
What to try this week
Send a request through your recommendation experience that can't be met within the stated budget. What you want back is a plain statement of what couldn't be found, with any pricier option shown as a separate, labeled choice.
