Second-hand
- r/Mechmarket Subreddit : check what is on offer (check the [EU] in the title), or post what you want to get and state that you are in EU.
- Ebay : you can find some second-hand keyboards, keycaps, and other components from UK or Germany
Chinese shops
- The bigger ones: AliExpress, banggood, Gearbest. Request to declare a lower price and/or mark as a gift (and hope for the best). The trick does not work with priority shipping (like with DHL)
- Amazon China
- TaoBao : Chinese language only and you usually need a proxy to locate a product and reship. Qtan is a famous guy who is a trustful proxy. He has also a site here: http://www.vendio.com/stores/E-sports-Gaming-equipments/contact and also sells on Ebay.
Japanese shops
i.e. if you want a Topre board or an Elecom Trackball
- Amazon Japan : priority shipping is usually around 8-15€ (5-7 days). Customs tax should be high but the last time we only paid 5€ for a 45€ trackball (maybe Amazon has found a way to import to another European warehouse first?)
