What we checked

We opened this offer on Philips’s own site at 6:35 AM ET on November 2, 2026 and recorded the price shown there. The figure above is the price we saw, not a price reported by a feed.

Philips lists $149.90 as the regular price, which makes $99.99 a 33% cut against the retailer’s own comparison. We quote that comparison as the retailer publishes it; we have not independently confirmed the item sold at $149.90 for any sustained period.

Philips has not announced an end date for this offer, so we do not print one. We re-check it every morning and remove it at the next check once it stops working.
