You have to pick and choose the type of product that is appropriate to buy (and ship from China), but there's definitely a bunch of opportunities here. Most items ship with China's 'developing nation' international post subsidy, so with free or very low freight charges, and they usually arrive in a ubiquitous grey plastic bag rather than a box. You can expect a lot of poor quality or knock-off products, clothing is usually one or two sizes smaller than for Western equivalents, but say you don't want to feel ripped off paying €15- for an HDMI cable in a local store, you can probably get something quite suitable for less than €2-. You just have appraise the reviews carefully, check the product descriptions and be patient (usually 2-4 weeks for delivery). The website itself is quite poor, slow, awkward logon which doesn't remember credentials well, the payment system is ok, but messages don't forward to email, you have to check their integrated system and support is pretty much non-existent. The claims procedure is fairly good though. But comparing to Amazon is like comparing a $2- shop to an Apple store... Who doesn't like rummaging through a cheap shop though! So think about what you're buying, perhaps try to be conscious of the impact on the world and the people producing these products, and find a place for Aliexpress in your retail therapy.
