So i saw, there are maby auctions right now on the german amazon site.
for example https://www.amazon.de/Anker-PowerCore-Powerbank-Kapazität-Technologie-Schwarz/dp/B00VJT3IUA/ref=mp_s_a_1_3?__mk_de_DE=ÅMÅZÕÑ&qid=1533803791&sr=8-3&pi=AC_SX236_SY340_FMwebp_QL65&keywords=anker+powerbank&dpPl=1&dpID=31I8mgwj14L&ref=plSrch
If you buy this, i can choose between 3 things, one of them is 15% off rhe bluetooth receiver and so on
sharing is caring!
Thanks for sharing.
