Mixed experiences on teambuy.ca ("TB") for me. Beware #1Marketing language. I've purchased a few items thinking they were the branded item but instead received knockoffs. Avoid deals where the merchant is Tree Top Shop, both of the deals i got from them were knockoffs. "Oral-B compatible toothbrush heads" is not the same as "Oral-B toothbrush heads" - perfectly legal marketing practices, but what I find slimely is TB's responses to brand-related questions.On a discussion board, someone asked "What is the brand? Or is it a no-name brand?" and TB's answer was "It is branded as "Your EX" (as morbid as that sounds) from Tree Top Shop." Honestly, just say that it is not the branded item (it wasn't, I purchased it), people can see right through your answer anyway, I wish i had seen the Q&A before I made the purchase! FYI, the branded item is under the brand "THE EX" rather than "YOUR EX". Beware #2The posted "original value". It is almost always super inflated.As for customer service, I had a deal where you had to schedule the class at purchase but then was told later by Teambuy that they made a mistake on availabilities and we had to reschedule. This was a pain in my a$$ and I asked them for compensation and received $10 in teambucks. The class itself was fantastic. Basically, TB gave me compensation for my inconvenience so that's great but their service definitely need improvement (i felt like I was dealing with a teenager who doesn't have much experience and is given rehearsed lines... like telemarketing. TB's online posts read the same way as well)Overall, I don't feel like I've gotten amazing deals from this site, but I've certainly gotten good deals. Read the deal carefully to make sure you're getting what you think you're and research the merchants, and you should be fine.
