March is the selling season.
As the selling season is drawing near, the market is going to go up.
Shipment should be made before October, otherwise we are not able to catch the selling season.
"As the selling season is at hand, lots of fresh orders will pour in."
As you know, June is the right season for the goods, so if they arrive later than June, we will miss the selling season.
We need the products in less than one month in order to get ready for selling season.
Could you possibly make your delivery date not late than May? You see, June is the right season for the goods. If they arrive later than June, we will miss the selling season.
