I got a number of suppliers to quote me their best prices.

我有一些供应商给我开出最惠。

For purchase of two LOC Liquid Organic Cleaners (High suds or Regular), you can use this coupon to buy one LOC Towelette at special price HK$70 (Original Price DP$80).

日起凭券购买灵验多种用途浓缩洁剂(强泡沬或标准装)两支，可以惠HK$70购买「灵验多种用途湿纸巾」一盒(4包装原DP$80)。
