I have just checked coupons. The lowest price I could get is 92.99 USD for Channel 50MHz Oscilloscope (in Banggood). Basically copy coupon, view price history or create e-mail price alert. What is the best price?
Latest coupon and price update (UTC):
Banggood (92.99 USD)
Banggood warehouse is located in China. CouponsFromChina software could not find any coupon for this product in Banggood. The question is – is it a good price? Maybe there’re no more promotions for this item, because current price is higher than average (which is equal 88.32 USD)

There were country-specific coupon codes published on Couponsfromchina social channels and price alerts. Coupon price may vary by country, because there’re different VAT rates, shipping cost etc. There is a chance that some latest coupons are still working:
