Quick answers

Should I choose the cheapest option?

Not automatically. Compare the features that affect how you will use the product, then use price as one part of the decision.

Why do retailer search results change?

Availability, sellers and prices change frequently. Search links let you review the current market instead of relying on a stale single-product URL.
