Common Pricing Misconceptions
Several myths persist about FX-991EX pricing that warrant clarification:
- “The price varies by color”: False – all color variants (black, blue, pink, white) maintain identical pricing. Color availability may vary by retailer.
- “International versions are cheaper”: Partially true but risky – Asian models (FX-991ES) lack some English menu options and may not be exam-approved in all regions.
- “Older models offer better value”: False – the EX series includes significant hardware upgrades (processor speed, memory) that justify the premium over previous generations.
- “Bulk purchases yield huge discounts”: Only partially – discounts typically cap at 10% for 20+ units, making individual purchases more economical for most buyers.
