maybe they merge this box in water or use dryer to get the tape off. I think the 纸质网眼胶带is the best for seal the package. it is hard to use and must use with water to seal.
in general, broker is wholesale and direct lender is retail. So wholesale will have lower rate than retail for sure. Within the wholesale, broker has different tier level too, such as tier 1, tier 2 and tier 3.....etc. the higher the tier, the better the rate or rebate. Even with same tier, broker has different compensation ratio with lender, such as 0.75%, 1%, 1.125%....etc With the same compensation ration, broker/agent has different commission shares... So, you can see, even you get same rate, the agent/broker might not get the same pay at the background :)
