Reliable whitening, small shipping issue

I ordered a Philips Zoom DayWhite kit and some extra gel refills. The products themselves were exactly what I expected, very effective, and the instructions were clear. The price was competitive, especially with the bundle deal I snagged. My only small gripe was that the tracking update was a bit slow, so I wasn't exactly sure when it would arrive until it was practically at my door. Still, it got here within the estimated time, so no real complaints. I'd shop here again for sure.

Good price, quick delivery

I bought some Opalescence PF gels during a sale. The multi-pack discount was really good, making it much cheaper than my dentist. Shipping was free and it got to my place in Melbourne in about 4 days. Definitely felt like I got my money's worth.

Hey guys, wondering if the Philips Zoom stuff from Whiter Smile is legit? Heard some places sell fakes.

B Beth Hughes 1 month ago

Yeah nah, I've bought from them a few times, always genuine. Expiry dates are good too, not like some other dodgy sites.

M Marcus 1 month ago

I was worried about that too! But my dentist actually recommended them, said they're an authorized retailer or something. My NiteWhite came sealed and everything, no issues.

Can I stack a first order discount with the free shipping offer? Or is it just one code per order?

S Sarah J. 2 months ago

Nah, pretty sure it's just one promo code at a time. The free shipping over a certain amount usually applies automatically though, so you can still get that on top of your first order discount if your cart hits the minimum.

R Raj Patel 2 months ago

Only one code. I tried to combine a student discount with a holiday one once and it wouldn't let me. Free shipping usually just happens though if you spend enough.

How long does shipping usually take to Perth? Need some refills kinda fast for an event.

L Laura T. 1 month ago

Hmm, to Perth from over east could be a few days. I got mine in Sydney within 3 business days, so maybe 5-7 for you? They do have express post as an option, might be worth looking into for that.

O Omar Kaur 1 month ago

I'm in regional WA and it took about a week, I think standard shipping. For Perth specifically, probably a bit quicker. You could ask their customer service, they're usually pretty responsive.

What's the go with returns if the whitening gel gives me crazy sensitive teeth? Had that happen with another brand once.

S Sophie 2 months ago

That's a tough one because I don't think they take returns on opened products for hygiene reasons. For sensitivity, maybe try a lower strength gel or use a desensitizing gel with it. They sell those too.

N Neil Torres 1 month ago

Pretty sure once you open it, it's yours. Maybe check their returns policy page, but with personal care items like that, it's usually no dice once used. Could be worth contacting them directly though, sometimes they're flexible if it's a real issue.

Anyone know if they do much around Black Friday? Thinking of stocking up on gels.

J Jared 1 month ago

They definitely do! I got a good deal on Opalescence gels last Black Friday. Keep an eye out closer to the date, they usually advertise it on their site or through email.

M Mark G. 1 month ago

Yeah, they have sales for all the big ones - Black Friday, Christmas, EOFY. Worth waiting if you can, usually better than the standard 10-15% off codes.
