Meleager pays as well and follows the others 

You easily unhitch the oxen and cart, following the road toward Barthes Provisions. As you walk in, a teenage boy greets you "hi. Can I help you find anything?"

Barthen's Provisions is a large warehouse stocked wall-to-wall with basic supplies and travelling gear. Pickaxes, rope, travelling clothes, etc.

"Aye boy, we have business. Gundren sent us with some supplies, they are out front." Stonegrin begins looking at the wares that the store offers to see if anything catches his fancy.

"Sure...if you need help finding anything, let me know" the boy says.

He turns and shouts into the back room "Mr. Barthen, your shipment is here! Alden, come help!" He and another boy then go out to the cart and begin unloading the goods.

An older man, in his fifties, emerges from the back room. "I see you've made it!" His smile turns to confusion "Where's Gundren? He was supposed to deliver these goods."

Noticing the additional crates bearing a curious seal Alden pipes up "These are meant for The Lionshield Coster. Are we unloading these here as well?"

"No, no." Barthen answers the boy. "Go have your brother inform Ms Graywind that her shipment is here. Hurry now, she'll be closing up any minute!"

The second boy hears the instructions and tears down the road.

There are no weapons or armor for sale or trade here, but many other supplies.

"Gundren and his guard Sildar were taken by a band of goblins run by a bugbear on the road here, we found Sildar in a nearby cave but Gundren has been taken elsewhere." Stonegrin motioned to the cart outside, "Found those crates with the blue seal with the goblins as well."

"Oh, my! His brothers have been camping outside of town for a ten-day. I'll have to tell them when they return for resupply." 

"Well, a deal is a deal" he says as the last of his supplies are offloaded from the cart. He offers 10 gp to each of you, adding "Liene will be waiting for you at the Lionshield Coster. You'd better hurry, it's getting dark!"

//everyone don't forget to add your payment for the goods

Meleager is happy to receive at least some payment , then adds

Eeehm, who is Liene by the way, we know nothing of this lion coasters?!?

Mitsu nods, looking suspicious.

“The Lionshield Coster is on the south side of town. Lienne is the proprietor there. She’s been expecting these goods for a number weeks.... I imagine you were not tasked with their return knowingly. If you take them to her, I’m sure she will show her gratitude." Barthen explains.

"Follow the road south, it’s just past the Stonehill Inn. I’ve sent a boy to let her know of your arrival."

Ah, thanks 

says , then to the others

lets head to this lion thing, I say. But Stonegrin, if you don’t mind to scout out just for curiosity... I don’t want no surprises, see

Stonegrin nods to Meleager then turns his attention back to Barthen, "I might be back after we secure payment from Lienne, looking to upgrade my Axe, unless there's a smith in town who'd be better to speak with regarding that?" 

"No, no smithy out here in Phandalin. We get most of our goods carted in...that is- when the carts  actually make it. If you're looking for weapons and such the Lianne is your best bet."

"Thank you, I guess we'll be on our way then, right lads?" Stonegrin says, heading for the door, "...unless any of ya need anything?"

Mitsu shakes his head. He's ready to get this done.

Go Stonegrin go

You make your way to the south end of town, just passing by the Stonehill Inn, you see the shop as described by Barthen.

Hanging above the front door of this modest trading post is a sign shaped like a wooden shield with a blue lion painted on it.

Meleager has no doubts anymore 

well, we can make our triumphant entrance or not?

Mitsu rolls his eyes, opening the door and walking inside.

Mitsu

Before you have a chance to open the door yourself, it swings wide and your momentum carries you over the threshold. Before you stands a human woman in her mid-thirties. You are now staring down the wrong end of a heavy crossbow, it's bolt knocked and pointed squarely at your chest.

"Who are you? What do you want?" She demands sharply.

The teenager Barthen sent ahead speaks up, peeking from behind the open door. "Ms Graywind, these are the newfolks I told you about."

It is at this moment she notices the rest of you, and the cart full of supplies. She takes a moment to glance over the lot of you, before lowering her weapon. "It's about time you showed up!" She then closes the door, locking it from the inside. She walks over to the wall, lifting a large wooden plank from the wall. You then see a larger door open wide. 

"Well, come on. I've been waiting for this shipment for weeks!" She helps guide the cart into the loading area, and closes the large doors, replacing the large wooden lock.
