ClearRetain has the one-dollar headline-price edge and a detailed fit/refund policy. SportingSmiles has a 90-day published warranty, free extra putty/trays after documented impression problems, optional lifetime digital scan storage and a dedicated retainer subscription. We would choose based on repeat-purchase workflow rather than $1.

Best for one-off replacement
ClearRetain has the stronger price-first pitch and a detailed public return/remake framework. If you simply need one new set and do not care about subscription infrastructure, it is difficult to separate these brands on price.
Best for recurring replacements
SportingSmiles has the more explicit recurring ecosystem: subscription, digital scans kept for life, reorder products and bundles. That can reduce friction for someone who knows they replace retainers frequently.
Compare your replacement schedule
With a $1 upfront difference, the result is driven almost entirely by future reorder price and frequency. Edit those assumptions directly.

Change the assumptions
Use a preset, then change any number. This is a cost model—not a recommendation about how often a dental appliance or brush head should be replaced.
