  I'm Greek, I buy stuff online with cc/debit without an issue (for example this month I paid scaleway, amazon, bookdepository etc) . Haven't tried aliexpress recently though.

  Yea depends on what category each company is listed at.
  Btw seems aliexpress processes orders even if payment is unsuccessful, as a result just saw I had like 4-5 orders pending for the same item

  If you're into bitcoins, see http://techcrunch.com/2015/11/18/mining-and-learning-with-the-21-bitcoin-computer. Bad investment, but it's a rasperry pi.

  @hawkjohn7 try some of these settings and let me know if this improves it for you any:

  echo 912000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_min_freq
  
  echo 912000 > /sys/devices/system/cpu/cpu1/cpufreq/scaling_min_freq
  
  echo 1008000 > /sys/devices/system/cpu/cpu0/cpufreq/scaling_max_freq
  
  echo 1008000 > /sys/devices/system/cpu/cpu1/cpufreq/scaling_max_freq
  
  echo ondemand > /sys/devices/system/cpu/cpu0/cpufreq/scaling_governor
  
  echo ondemand > /sys/devices/system/cpu/cpu1/cpufreq/scaling_governor
  
  echo 25 > /sys/devices/system/cpu/cpufreq/ondemand/up_threshold
  
  echo 1 > /sys/devices/system/cpu/cpufreq/ondemand/io_is_busy
  
  echo deadline > /sys/block/sda/queue/scheduler # Please note use your drive in place of sda if different

  If you are using this over network:
  
  echo 1 > /proc/irq/$(cat /proc/interrupts | grep sw_ahci | cut -f 1 -d ":" | tr -d " ")/smp_affinity
  
  echo 2 > /proc/irq/$(cat /proc/interrupts | grep eth0 | cut -f 1 -d ":" | tr -d " ")/smp_affinity
  
  echo 2 > /sys/class/net/eth0/queues/rx-0/rps_cpus
  
  echo 2 > /sys/class/net/eth0/queues/tx-0/xps_cpus
  

  Some tweaks for the Banana Pi (A20) that I have found useful.

  Note: these reset each boot usually, but you may also want to cat each one for their default value before changing it just so you know what you're changing

  Cheers!

  I hope I am not breaking any law :-)

  @noaman I have a policy of not using paypal or any other payment for people I don't know in RL, plus since atm I can only use paypal for cross country transactions...

  Still you can pm me and tell me what it was you wanted but 90% + I will prolly have to say no
