I have a wood dining table that I bought a few years ago for 800 dollars. I had it covered with a sheet, but I also put some of those grip liners beneath the sheet to avoid it slipping off. Fast forward 3 years and I decided to remove the sheet permanently and I found that there are hundreds of small bubbles in the table where that grip liner was. Is the table now trash or is there any way to remove these? Thanks

I am trying to save some money to buy a car and while I do work, it is not enough to get a car any time soon. I started buying firesticks and reselling them and I have made some good money, but they are currently sold out. Do you guys have any ideas about what things can be resold for a profit? I currently do older video games as well. Thanks

Im trying to start a small business where I buy from online auctions and resell. I have registered for an EIN and when I try to register my business it is asking if I want to register sales tax and then asking for my estimated monthly payment for sales tax is? I was under the impression that being tax exempt is free. Is this the wrong section or what should I do? Im in michigan if that helps. Thanks

Im a resident of michigan and I am thinking about buying pallets of store returns/liquidations and reselling them for a profit (hopefully), but I need help with the steps to go about this. I am seeing that I need a resellers permit. I was wondering where I apply for one, what info I would need, and if I need anything else before I can start. Thank you in advance.

Im 19 and a college student and I was looking into reselling stuff to make some money to help pay for college. After some research I see that I need a tax id (EIN) and a resale permit. I was wondering will obtaining any of these things affect my financial aid or taxes. I currently have no income so I have nothing to file. I will of course file if I do make a profit, but will just having these two things affect me at all? Thanks

I was looking to make some extra money on the side by buying wholesale and selling for a profit. My main idea is to sell cell phone cases, but I also found a good deal on some fake Louis Vuitton belts. All of the goods come from china and I want to make sure before I do anything illegal. Is it against the law to sell these online or at a local flea market if the buyers know the item is fake. The only reason I ask is there is a man at that flea market who has been selling fake michael kors handbags for years and has never been told anything by any of the cops that visit the flea market. Thanks

It is a hip hop or rap song and I remember hearing it on the radio. I believe it is by kanye west from his new album, but I cant seem to find it. The only part of the lyrics I remember goes something like this. They ask me pablo how... or they tell me pablo how... it is annoying me so much that I cant figure it out. Please help me. Thanks

I forgot the password to my windows live email and it wont let me reset it. In the settings on my iphone I can see that my email and password are entered, but the password is in black dots, so it cant be seen. Is there anyway to show the actual password instead of the black dots? I know on a computer I can inspect element, but is there something similar on iphone settings? Thanks

I live in michigan and the daily three numbers were 717. I chose the numbers 317. Is there still a prize for this? I see that the payout table says one off wins 34 dollars, but im not sure if thats what it means. Thanks

Is there any way to view everything from my icloud backup (messages too) on my pc? My iphone broke and I got a new android instead, but I would like to recover my old messages. It is backed up to icloud, but I cant find a way to view them without an Idevice. Thanks

I recently bought a 65" 4k ultra hd tv to replace my 50" 1080p tv. The problem is the picture is worse on this tv than it was on my old tv. Someone told me that the reason for this is probably because my cable channels are not 4k supported yet so they will appear blurry on a 4k tv. Is this true? My return period is about to expire and I want to know what I should do. Thank you

I am an 18 year old male and I am really skinny. I would like to get bigger by the time summer comes around in like 6 months, but before I can gain muscle I need to bulk up. I would rather not take any supplements. What foods do you recommend for me to bulk up? Any extra fattening foods to eat or make at home? Thank you.
