Wasn't the gift basket from a coworker? If the couple really felt the purpose of the event was to get money back for catering, why invite coworkers in the first place? For that matter, why invite the coworker and tell them to bring a guest? Sounds like the couple shelled out some serious cash by inviting everyone they were remotely acquainted with.
Seems like it's better to give nothing than to give something small, even if that's all you can afford. They may not notice if you don't give anything, but you'll catch grief if they don't like your gift.
When a friend/roommate of mine got married, I gave her a nice picture frame that I thought looked nice. I didn't spend a lot on it and I could've spent a lot more, but it wasn't really in my budget. Right after the wedding, she and some friends were writing thank you cards, and I overheard her complaining about some distant cousin that only sent her 20 bucks. Someone she never sees and who didn't attend the wedding anyway, yet she was insulted they sent her a mere 20 bucks when they were FAMILY. What does that mean for me, who was a roommate and close friend and who gave her what I thought was a thoughtful gift? That hurt.
