[DEAD] Friday: Monoprice M560 Planars + Tube Head Amp drop to $240 with Coupon AND $0.01+ filler item

This Friday coupon is over, but Monoprice has recurring coupons, so they’ll return. The main question is which headphones will be eligible for which coupons, which we can only find out when the coupons are live so we can “test” them live…

For Friday only (May 19, 2017), promo code HEAR20 gets you a 20% off discount on an order that totals $300 or more at Monoprice’s own website. Neither the M1060 nor the M560 on their own are eligible for the coupon.

However eligible is the Monoprice M560 Planars AND Stereo Tube Headphone Amp (PID 16154) bundle which goes for $299.99. If you add an extra item priced $0.01 or more, then you can use the coupon, dropping the price of the combo to $240. The M560s on their own go for $200.

Ideas on how to get to $300+
+ Metal 1/4″ to 3.5mm adapter for $0.75 – or any other audio adapter
+ 6ft TOSLink cable for $2 – or any other cables
+ 6ft premium RCA to 3.5mm 22AWG M/M cable for $3 – or any other cables
+ 8323 Closed Over-Ears for $16 before coupon
+ Retro Closed Over-Ears for $25 before coupon (Superlux/Samson clones; even though it’s a new release, it is coupon eligible!)

The following are not eligible, I just tested them in the shopping cart: the M560 and M1060 planar headphones, the 18515 Metal On-Ears, and the Triple Driver XXX Triple (what a goofy name!) earphones.
