A three-item scale measuring the tendency to abandon an online shopping cart in response to unexpected additional costs revealed at checkout — specifically shipping charges, sales tax, and the total order amount. Items capture a cost-shock abandonment pattern where the consumer's decision to not purchase is triggered by price information disclosed late in the checkout process rather than by price-based comparison shopping. Part of a four-scale battery examining distinct cart abandonment motivations.
7-point frequency scale (never / always)

Single reliability estimate: α = .91 — Kukar-Kinney & Close (2010, main study). VALIDITY: Convergent and discriminant validity evidence reported. Response scale anchored at 'never' (1) and 'always' (7). Scale was developed and refined across two preliminary studies before main data collection. NOTE: Three actual items; a fourth entry in the original is a scale administration note regarding the response scale format. Part of a four-scale cart behaviour battery alongside Cart Abandonment (Search for Better Price) (CASP), Cart Abandonment Frequency (CARF), and Cart Usage as a Decision Tool (CUDT) — all from the same study.
