Every gift I got was and still is priceless. It doesn't matter whether it's a 1,000$ check or a simple Christmas card. It is something that was given to me and I cherish it. It is more important WHO gives me something than WHAT was given to me. The persons I don't like could give me a real A380 and I wouldn't change my opinion on them.
The same thing happens when I give presents. Due to unpredictable economic situation in my country, there were days when I could give more expensive gifts and days when I couldn't, but every time I did give something without any reservations or otherwise I wouldn't have bothered going to the shop in the first place.
Interestingly, in my country it is considered as rude if you leave the price tag or receipt.
