We've used WegoShop for all our trips.

We loved Marge and they have great service.
They will buy anything from anywhere you ask them to.
Last time we were their they had to go buy a Fax machine for a couple that had to work during their vacation.
She will set up a delivery time to suit you.
We had to make a room change just when they had helped us unload 1/2 the items. She just put them back into the boxes and followed us up to the next room-no problem no complaint.
You can pay in advance and she will leave them with bell services.
You can use coupons or store cards if you want .
She gives you the receipt from the stores along with your bill.
If she has a question or can't find your specific item she will call asap on the cell to talk to you and ask what you want her to do. She will call you before your trip too if you need a change or she has a question.
You can email your list/stores to her beforehand
She even comparisons shops-2 small bags of Tostitos were cheaper than one large so she did that..etc.
BTW-last time we had so much food because the store was having a 'buy one get one free'sale on many of our items. She brought them along and appologized for overloading us but a sale was a sale.
Bell Services had a lot of snacks when we left

.
We have always been happy with WegoShop.
No extra fees and the personal service can't be beat.
