I would have to say a great benefit to working in the purchasing industry is being comfortable negotiating. My wife and I took a trip to Cancun and as anyone knows who has been to Mexico is that items sold on the street are subject to haggling. Our list of purchases...

Sandals- Asking $45- Purchased for $15
Dice Cup- Asking $55- Purchased for $20
Coin Purse- Asking $30- Purchased for $10
Jacket- Asking $30- Purchased for $18
Hat- Asking $10- Purchased for $8

There was also an excursion to Xel Ha which is an all-inclusive resort with plenty of activities. Our vacation planning service offered the trip for $119pp. The local agencies advertised the same trip for $95pp. My wife and I preferred to book with our vacation service because they offered a warranty on the trip. After discussing the local pricing they took off 10% and we booked the trip for $107 each.

More evidence that just about all pricing is negotiable!
