Giving the perfect father the perfect gift doesn’t need to cost you a fortune. Stick to his interests and get him gifts that complement those hobbies. No matter what the hobby, getting Dad a gift for under $20 is easy as pie.For The Gardening DadIf your father loves his lawn and landscaping, give him the gift of growth. Head to your local nursery or hardware store and talk with a gardening specialist about your father’s gardening likes and dislikes and buy him a small plant. Make sure you have information such as which way the part of the lawn you are buying for faces, how much sun the area gets and what other plants your dad has planted there. If you’re unsure, find a nice potted plant he can put on the porch or patio.For the Golfing DadFor the father who golfs, look no further than your local Golf shop. Plan in advance and buy your dad a great golf shirt at the end of the season, when you can find them on clearance. If you did not manage to plan that far ahead, get him a box of practice balls that he can use at the driving range.For the Woodworking DadDoes your dad love to build things during his free time? Think of how he stores his tools. If they are disorganized and cluttered, buy him hooks to hang on the wall and help him organize them. Not only will he love being organized, the time spent with you will be an added bonus for him.For the Sporting DadIf your dad loves to fish or hunt, look no further than your local sporting good store. Consider getting him a unique lure or a pair of thick, warm gloves for those days spent hunting. Remember, the point is to complement his hobby - so do not be tempted to overspend. He will think of you each time he uses his new item.For the Techie DadIf your father is a total tech head, buying gifts to fit this category can be tricky. Stay away from the main items, such as MP3 players, and instead look for accessories. Do your shopping online, as accessories are much cheaper at sites like Amazon.com or newegg.com than at brick and mortar stores. Grab dad a new case for his phone or a backup pair of headphones. He’ll thank you when he busts his good ones and needs a backup.For the Dad Who Has it AllIf your dad is one of those fortunate men who seem to have everything, take dad out for lunch. Chose a mid-range restaurant, such as Qdoba or Panera, and spend an hour just catching up. Chances are, this is the gift he will cherish the most: time with you.
