是买东西的数量:(很不厚道的引用我在黑曜的原话
)
在商店界面（就是有BUY，SELL的那个）按R键，神甫头象的右下会出现一组数字。。。
那数字就是你在他这所消费金额数值/10的数（卖不会计算）
所以只要在他这里买东西就好，不管买什么，买到一定数字就会出现新东西（出现的顺序及数字没记下来。。。）
所以在这里消费达到25W时（显示数字25000）就可以出现魔法F，十字巨剑等物品。。。。.
下面是在外国某网站找到的(之后别人找到的。...)

================================{ Shop Points }=========================[PNTS]=
Certain items don't show up in Vincent's shop until you do a certain amount of
buying and selling in your game.
You can check your current point total by pressing R at the main shop screen
(Buy/Sell/Item Display). For every purchase you make at any shop, you earn 10%
of the purchase price in shop points. Sales, however, yield varying amounts of
points depending on the mode in which the sale takes place: 100% over Wi-Fi,
50% over Wireless, and none using Vincent's shop.
The following items are unlocked by earning shop points:
1,000 - Powdered Milk
2,000 - Miko Dress
3,000 - Silk Negligee
5,000 - Feather Gear
10,000 - Paludamentum
20,000 - Spiked Mail
25,000 - Magical Ticket
30,000 - Holy Claymore
50,000 - Record 5
