My goodness, the Princess Bride has been watching way too many bridal programs on TV! She really is not entitled to make her wedding party miserable and broke.
Is Donald Trump her Dad? No? Wait until she starts opening up presents after the wedding, and starts seeing $50 in an envelope, and tea towels in boxes instead of the items off her registry list!
I'll tell you my sob story. A co-worker was getting married, I went to the store, got her registry list, and found flatware that she wanted. So I bought her 4 of the 12 sets that she had listed. I paid 1/2 price for it, and she did not know that. It cost me $80, more than I had planned to spend for a wedding where I was not going to be able to be there, and a woman I barely knew.
She caught me in a public place at work, and chastised me for only buying 4. If I had paid full price, and bought twelve that she demanded of me, it would have been $480!
So, dear, stay within your budget on presents. Buy one for her shower, and one for her wedding. You can buy something nice for a small price. I bought my little freezer ice cream machine for $10. What a cute shower present, and write out some recipes on note cards for ice cream or syrup. Even include a jar of sprinkles. My machine makes great ice cream!
Watch sales, and shop at discount stores like Tuesday Morning.
Think about kits, they are very popular, pick an appliance or a pan or a pot, and include what you need to cook with it. Like a pasta boiler, put in some cute pasta, a bottle of oregano or garlic powder, some tongs, and it will still be less than $25.
If you have good penmanship, or a way to do this on computer, hit your family up for tried and true no fail recipes, and write them on cute note cards. And give credit on the card to the cook, like "Aunt Sadie's Sunday Roast." And give her a cookbook, check the book websites for bargains, I got most of my cookbooks at bookstore sales.
You do not have to attend an out of town event. But don't get caught telling a lie about why! "I do not wish to take off of work" or I just can not afford it" are fine, and require no explanation.
If the bride goes psycho Bridezilla on you, remind her that you were a last minute addition to the wedding party, and a polite bride would have said up front what the cost[s] would be.
