Auction and second source sites
Sure, you can just look on eBay or BuyDig, but personally I prefer to buy from a place with a decent returns policy and a fair reputation. Too many reports of people buying from eBay and getting a different model than what they ordered (sometimes in the wrong box). Also note that some manufacturers (Aeotech is one) believe that everything sold on eBay is used and will not honor warranties for items purchased through this channel.
You can buy Chinese made items from AliBaba express. I myself don’t use this as a source – – too many issues with the product description, or even counterfeits. But a lot of people do.
Remember that for Zigbee, you want devices which are certified for Zigbee Home Automation 1.2 (ZHA 1.2). There are many Chinese zigbee devices which use other profiles and will not work with SmartThings.
The following vendors all sell a lot of home automation equipment, and have decent reputations. Return policies and shipping fee policies vary, so read those carefully.
In the US, 15% is a typical restocking fee for electronics products that have been opened and are not defective. UK restocking fees vary much more. Always read returns policies carefully before purchasing.
Aartech (Canada) https://www.aartech.ca/zwave . Good selection of zwave products. Offers warranty service which can be difficult for Canadians to get otherwise. Read the returns policy carefully.

Gets generally good consumer reviews, but you may have to get your credit card Company involved if you have a dispute.)

HA Vendors with weak returns policies
Sometimes you want to try a product even though you can’t find it at a vendor with a decent returns policy. The following vendors have been successfully used by some community members, but be aware it may be very difficult to return even a defective item unless you get your credit card company involved and refuse to pay for it. And even then you’ll probably have to pay return shipping.
BangGood. (Sells to many countries) (Chinese seller with a wide selection of products at low prices, including Orvibo zigbee sensors. Products are often misdescribed in the headers, so read details carefully. In particular, pretty much everything is titled as “Wi-Fi” even if it is really zigbee or Z wave. Shipping may be delayed by a month or more. Returns policy is limited to three days and requires that you take pictures of object to be returned. Some UK community members have had good luck buying Orvibo sensors from them; others have reported receiving defective devices.) www.banggood.com
Shop WiFi. (Good source for Taiwanese products like zigbee sensors not available elsewhere)
