Rest of the OpCodes , the structs, and the SQL..
Yes, code is a little sloppy, can be cleaned up a bit when databse stuff is implemented
Code:

cout << name << " is attempting to purchase an item.. " << endl;
Merchant_Purchase_Struct* mp=(Merchant_Purchase_Struct*)app->pBuffer;
// this item number needs to bounce back to the merchant table, since the client
// only tells us what slot the client is wanting to purchase.
// slot value is in mp->itemslot.
uint16 item_nr = 16592; // hardcoded to always sell you grapes :)
Item_Struct* item = database.GetItem(item_nr);
// Give Item
APPLAYER* outapp = new APPLAYER;
outapp->opcode = OP_ShopGiveItem;
outapp->size = sizeof(Item_Struct);
outapp->pBuffer = new uchar[outapp->size];
item->common.number = mp->merchant.quantity; // number purchased from merchant.
// copied this code from loot code - but doesn't seem to work right.
item->equipSlot = 0xFF;
for (int i=22; i<31; i++)
{

break;
