Costco Electric Toothbrush: Bundles, Deals, and Member Value
Costco consistently offers some of the best electric toothbrush deals available, especially on Oral-B and Sonicare bundles that include extra brush heads. Their exclusive bundles typically save 20-35% compared to buying the same items separately elsewhere. The 90-day return policy adds extra peace of mind.
Costco is one of the best places to buy an electric toothbrush if you are a member. The warehouse retailer negotiates exclusive bundle packages with Oral-B and Philips Sonicare that include extra brush heads, travel cases, and sometimes multiple handles for families. These bundles offer genuine savings that are difficult to beat, even during Amazon sales events.
This guide covers what is currently available at Costco, how to evaluate whether a bundle is actually a good deal, and when you might find better pricing elsewhere.

Are Costco Bundles Actually a Good Deal?
Let us break down the math on a typical Costco electric toothbrush bundle to see if the savings are real:
Example: Oral-B iO Series 5 Costco Bundle
| Item | Retail Price (Amazon) | Costco Bundle |
|---|---|---|
| Oral-B iO Series 5 handle | $120 | Bundle Price: $130-140 |
| 4 extra iO brush heads | $40 | |
| Travel case | $15 | |
| Total retail value | $175 |
Savings: $35-45 (20-26%)
Example: Sonicare ProtectiveClean 2-Pack
| Item | Retail Price (Amazon) | Costco Bundle |
|---|---|---|
| 2x Sonicare ProtectiveClean handles | $140 | Bundle Price: $100-110 |
| 4 extra brush heads | $30 | |
| Total retail value | $170 |
Savings: $60-70 (35-41%)
In most cases, yes, the savings are real and significant. The two-pack bundles in particular offer outstanding value since you are essentially getting the second handle at a steep discount.
